SMILES import handles CACTVS-type representation of coordinate bonds ('|' character).Please note that the export does not handle it.
Terminal H and OH are added to nucleic acids by nucleic acid import.
Name to Structure (n2s)
CAS Registry Numbers® can be converted to structures even when they contain coordinate bonds¹.
Conversion of nitrogen-substituted acetohydrazides is now supported.
Elements with isotopes, such as (14)C, are converted in name to structure by default, and, optionally, they can be converted with document to structure using the "d2s:elements" format option.
Some OCR errors have been fixed in carbon ranges for homology groups, for example, "Ci_10alkyl".
Generic structure names (such as "alkyl" in English) are supported in Chinese as well, for instance, N-???-4-??? and C1-C4-??.
Polyspiro names with a polycyclic component, such as dispiro[cyclohexane-1,2'-indene-1',2"-imidazole], are supported.
Document to Structure (d2s)
For enzymes with a substrate in their name, such as "serine protease", the substrate (serine) is not converted by default.A new format option, "d2s:substrates", enables the recognition of the substrate in such cases.
New format option "d2s:specific" has been added to convert only specific structures.This option excludes structures with R-groups from the conversion.
More OCR error correction is performed.
In the case of processing XML fragments not starting with "<?xml version="..."?>", it has become possible to specify that the input text is in XML format by using the "d2s:content-type=application/xml" format option.
Metadata is also extracted from older (since 2001) USPTO patents in XML format: the section where a name is found is recorded as metadata (title, abstract, description, or claim number).Furthermore, document metadata is extracted as well: patent title and ID, inventors, IPC categories.
OCR error correction has been added for Chinese names.
Structure to Name (s2n)
In fused ring systems with an atom being in a non-standard valence state, the generated name conforms to the IUPAC rules by using the lambda notation only in front of the fused names and not inside the component name.
See for instance: 1H,3H-2λ4-naphtho[2,3-c]thiophen-2-one.

Bug fixes:
MarvinSketch GUI
MSketchPane setPiece(Molecule) method did not work; it set the molecule on the canvas instead of putting it on the cursor.
Starting points of electron flow arrows drawn from radicals and/or lone pairs were changed when lone pair visibility was switched off and then on again.
R-logic label was not taken into account by zoom action even if visibility option "R-logic" was switched on.
Painting
Electron flow arrows starting from an atom, a negative charge, or an automatically calculated lone pair disappeared when lone pair visibility was turned off and then turned on again.
Editing
Menu option "Link Node" was not disabled when an atom had less than two bonds.
A contracted tripeptide disappeared from view when it was expanded, but 2D Clean brought it back.
It was not possible to draw an electron flow arrow from an atom to an incipient bond between this atom and an abbreviated group.
Erasing a structure without an R-group attachment left "1" on the canvas, which behaved as an atom.
When an atom was selected and the "R-group attachment" button of the Markush toolbar was used, the selected atom was changed to an R-group attachment point; however, a new R-group attachment should have been added to the selected atom in this case.
Dragging with the R-group attachment tool, a bond was created connecting two R-group attachments.
Using the R-group attachment tool, R-group attachments could be added to an existing R-group attachment.
Load/Save handling in UI
Lone pairs were lost at "Copy As...> PDF" at Mac OS X.
PDF export did not use the color scheme setting.
Clipboard handling
During PDF export, atom labels were turned upside down with some font types.
MarvinViewGUI
Import/Export
MRV/CML
After MRV export and reimport of a structure, its text box font color turned into the frame color of the text box and the font color turned to a not defined color (black).
Format recognition
'(S)-(-) Propanolol' was recognized as SMILES.
Chemical Registry Numbers® were recognized as MDL MOL format.
Name to Structure (n2s)
Automatic format recognition failed for names using unicode hyphens.
Names of some spiro compounds containing aromatic components were not converted.See, for instance, 6-(2, 5-dimethylphenyl)-5'-methylspiro[chroman-4,2'-imidazol]-4'-amine.
Document to Structure (d2s)
Some names containing a space character (for instance, "malonic acid") were not detected.
When using document to structure using the MRecordReader API, the MRecord.getMolString() method returned null.
The character position property of recognized names was sometimes wrong.
Spiro and fused ring system names were not recognized in HTML documents when the brackets were represented by HTML entities.
Processing an HTML document failed when the document was declared to be in XHTML format, but was not actually a valid XML (for instance, contained unclosed tags).
Processing a USPTO XML patent file in the current directory failed when it referred to CDX structures files.
Some structures embedded in Office documents were not extracted.
Structure to Name (s2n)
Names could not be generated for structures with lone pairs (MolAtom.LP).
The name generated for OH- was "oxidanide" instead of the preferred form "hydroxide".
An extra locant was included in the name of cyclic structures with multiple hetero atoms with one of them having non-standard valence, for instance, 1λ6,4-thiomorpholine-1,1-dione instead of 1λ6-thiomorpholine-1,1-dione.
In cases where a cyclic substituent was connected indirectly to the parent through an ether, sometimes wrong names were generated.
Name generation failed for structures with a methanethione parent.
Molecule representation
java.lang.ArrayIndexOutOfBoundsException was thrown when a multicenter atom being the only member of an S-group was removed.Valence Check Valence Check did not accept chlorine and heavier halogens with 1negative charge and with 2, 4or 6pieces of fluoride ligands.
Stereochemistry
Incorrect stereogenic center was found in some spiro compound.

New features and Improvements:
MarvinSketch GUI
Peptide cycles and bridges can be drawn according to IUPAC recommendations.
IUPAC numbering can be displayed on the atoms of each molecule using the "View > Advanced > Atom Numbering > IUPAC Numbering" menu item.
Lone Pair (LP button) was removed from the "Special nodes" group of the "Periodic Table > Advanced" tab, so it cannot be reached from the GUI anymore.
MarvinSketch Menu
The "Calculations > Predictor" menu option has been removed from the default Marvin menu.
Painting
Drawing of electron flow arrows has been changed.Single electron flow arrows can now start either from a radical or from an electron of a lone pair.Electron pair flow arrows can only start from lone pairs.
Atom property values belonging to the same atom are now separated with semicolons instead of commas.
When lone pairs were displayed on a structure, the charge symbol was nearly invisible.
Load/Save handling in UI
The same last-used folder is saved for the "File > Open" and the "File > Insert file" functions.
Graphical object handling
Electron flow arrows can be started from or targeted to multicenter atoms.

New export option, cc, is introduced to V2000 export in order to write absolute chiral flag if there are only ABS enhanced stereo labels in the molecule.
New import option, z, is introduced to MDL import that converts carbon atoms with "Z" label to R-group attachment points.
SMILES/SMARTS
[Z] is imported as R-group attachment point from SMILES.
CXSMILES/CXSMARTS
New export option, b, has been introduced to CXSMILES/CXSMARTS in order to turn off the export of bicyclostereo-information.
Name to Structure (n2s)
Name and corporate ID resolution webservice now supports NTLM authentication.
Names with a missing dash before the suffix locants are now recognized.
Non-standard IUPAC specification of stereochemistry inside suffix locants is supported.
Names with superscript locants of a bridged ring system numbering are denoted by spaces are now supported.
As a result of numerous Improvements: to the systematic name conversion algorithm, more names are converted by n2s and detected by d2s.The accuracy of structure generation has also increased.(For instance, 5% more names were detected and converted in a large, diverse set of patents.)
An example custom dictionary has been added to the documentation.
Document to Structure (d2s)
Chinese names are now detected in text documents using an approach which recognizes names in Chinese sentences without the spaces that separate words in English.
In addition to OSRA, the CLiDE and Imago Optical Structure Recognition tools (Chemical OCR) can be used to convert images to structures.These tools need to be installed separately from Marvin.
When processing USPTO patents in XML format, the section in which a name is found is recorded as metadata (title, abstract, citation, description, or claim number).Additionally, document metadata is extracted (patent title and ID, inventors and assignees, IPCR categories).
When processing a USPTO patent XML document, referenced CDX files are imported automatically if they are in the same directory as the XML file.
Processing of USPTO XML patents has become faster: an average 20% speed-up, more than ten times faster process for some patents.
PDF document pages with images in the JBIG2format are now supported.
PDF documents generated by Adobe Acrobat Paper Capture Plug-In and ExperVision are now handled specially, since they contain both an original scanned image of text and the text resulting from OCR of the image.This allows much faster processing of such documents, and avoids double hits for the same text.
PDF documents with many small high-resolution images are now processed much faster, even when Optical Structure Recognition is used.
The document creation date property is stored as a java.util.Date object instead of string.
Structures returned by image recognition tools (OSRA, CLiDE, Imago) are better filtered to avoid false positives.
OCR processing for scanned texts can be disabled using the -ocr format option.
Processing of PDF documents with scanned black and white images ( e.g. , most non-searchable patent documents) has become approximately two times faster.
Structure to Name (s2n)
When retrieving a Chemical Registry Number® from , the InChiKey of the structure is used to search for the structure.This allows more structures to get a number in such cases where several different SMILES with chemically irrelevant differences are associated with the structure.
Molecule representation
New method, SelectionMolecule.addAtom(MolAtom, boolean), is introduced.
New methods, MolAtom.getBondArray() and Sgroup.getBondArray() are introduced.
Calculations
NMR (CNMR, HNMR Prediction...)
Various phosphorus-proton spin-spin coupling parameters have been added to the predictor database.
Geometry (Topology Analysis, Geometrical Descriptors, PSA, MSA)
"Fsp3" option has been introduced in the Topology Analysis plugin for calculation of sp3 carbon atom fraction.
Elemental Analyzer
Charge is taken into account in atomic mass calculation.
Chemical Terms
Chemical Terms's (CT) Structure Checker functions accept XML configuration as string parameter, thus Structure Checker XML configurations can be used in JChem Cartridge via CT.
New checkErrorCount Chemical Terms function returns the number of errors/issues found by the checker(s) in the configuration.
Structure Checker
Checker "substructure checker" has become available in Marvin Beans, so installing Marvin Beans will install the fully functional Structure Checker application.
Set Structure Checker configuration can be copied to the clipboard as action string from Structure Checker GUI and Structure Checker Editor.
The "excluded" list of Structure Checker's Abbreviated Group Checker accepts quotation marks in command-line.Possible definitions can be the following: "abbrevgroup:excluded=Ph,Ala,Gly", "abbrevgroup:excluded='Ph,Ala,Gly'" or "abbrevgroup:excluded="Ph,Ala,Gly"".
The checkers and fixers can be localized or customized according to individual requirements.
Build/Installation
Mac OS X installer images were not digitally signed, and GateKeeper in newer OS X versions (10.7.5+) reported our installers as damaged and refused to install them.
Bug fixes:
MarvinSketch GUI
Aliphatic/Aromatic atom query property had three options ("a", "A", and "A,a") instead of the necessary two ("a" and "A").
MarvinSketch Dialog
In case of long names, only a part of the whole name appeared on the naming panel.
Editing
Deleting an atom having an R-group attachment did not delete the attachment.
The end of an arrow did not stick to the midpoint of an existing arrow.
Load/Save handling in UI
In MarvinView, "File > Save All...> Advanced > Into SEPARATE FILES" did not save the last structure.
History functions
When the "Stereo" atom property had been changed, Undo/Redo did not work properly and the IUPAC name was not updated.
Graphical object handling
Labels written in text box were shifted when they were pasted either as an OLE object or as a PNG image.
MarvinViewGUI
When a structure which contained an R-group definition was opened from MarvinView for editing in MarvinSketch, the structure appeared with 0% zoom factor.
Text elements (atom labels, atom indices, text box contents, IUPAC name) were not resized in MarvinView while zooming the structure using the "View > Transform > Zoom" function.
Printing in MarvinView
When choosing "Print > All Visible", the structures overlapped in the preview, and "Print > All Visible > Print to PDF" resulted in an empty file.
MarvinSpace
A bug occuring at PDB import has been fixed.
The "Edit > Cut" menu option has been fixed in the MarvinSpace menubar.

Aliphatic and aromatic query property, when they are used together, is not imported and exported any more.The "no property", no aromatic or aliphatic query property, has the same meaning.
Only lower case file extensions were recognized.
MRV/CML
MRV files that contained circular R-group references without attachment point information could not be imported.
MOL, SDF, RXN, RDF
Export of structures containing multicenter S-groups to format MOL V2000 resulted in a non-standard file.
Newline characters in molecule name were not escaped.
MDL MOL import did not use MDL valence model for non-charged metals.
Atom list embedded to atom list in MDL file formats resulted in invalid atom list elements after import.
CDX/CDXML
Reactions containing anonymous alternative groups were not imported from CDX format.
XML files with complex header could have been recognized as CDXML.
SMILES/SMARTS
Query Hydrogen atom with parity definition confused SMARTS import.
SMILES export did not throw exception when the molecule contained not supported reaction stereo information.
Newline characters in molecule name were not escaped.
SMILES import read Meitnerium atom (Mt) as any atom (*).
Strings containing valence property were recognized and imported as SMILES instead of SMARTS.
CXSMILES/CXSMARTS
Import of CXSMILES/CXSMARTS strings that describes the coordinates of atoms with option c added 'CIS OR TRANS' stereo information to double bonds in small rings.
Single or aromatic bonds could be lost during CXSMARTS export and import.
InChi/InChiKey
InChI was not recognized in MolConverter as one line molecular format that can be given as the argument of -s option without specifying the format.
Reactions could not be exported to PDF.
Name to structure (n2s)
Names with a cis- or trans- imine bond were failing to be converted to structures
Ions, such as "bismuth(3+)", were imported with valence property set to 0.
Ortho substitution on acetophenone generated wrong structures.
Some E/Z and R/S stereochemistry was missing in structures imported from names when the locant of the atom or bond with stereochemistry was not specified explicitly.
The "H-" ion was missing from names containing "hydride", e.g. , sodium hydride, they only had e.g. , "Na+ instead of the correct NaH.
Names containing atoms with both a non-standard valence (λ) and a positive charge were converted to structures with an extra implicit hydrogen on that atom.
Primary and secondary amine oxides were represented as N-OH instead of [N+]-[O-].
The "Name" format was not automatically recognized for names with XML/HTML character references, such as "&##946;" or "α".
In some cases, amino acids with α, β, and γ prefixes were not converted.
Using n2s in the applet required the downloading of an unnecessary component.This, in turn, made the first applet usage much slower.
Document to structure (d2s)
Some common words such as "DUST" or "crank", were recognized as names because, e.g. , DUST is a rare acronym for a chemical structure.These words are now ignored.
The insideTag format option was not working for XML and XHTML documents.
Some uppercase words were mistakenly recognized as SMILES strings, such as "CISCO" or "ON-OFF".
Some embedded images were returned with 'PNG' type instead of 'OSR', and the usual OSRA options and properties ( e.g. , timeout, confidence filtering) were missing as well.
When d2s was interrupted (for instance, by a timeout), an OCR or OSR process could be left running in the background until it was completed.In similar cases such processes are now stopped immediately.
Extracted names sometimes contained some irrelevant characters at the end, such as "4-(trifluoromethyl)-2-((1H-1,2,4-triazol-1-yl)phenyl)-methanamine 2e" instead of "4-(trifluoromethyl)-2-((1H-1,2,4-triazol-1-yl)phenyl)-methanamine".
In some cases, single names separated by space were imported as if they were one compound, for instance, "2-hexanoyloxyethyl 1-formyloxypropyl".
Embedded structures in Office documents were always imported with the absolute chiral flag set.
Structure to name (s2n)
When generating names in parallel in multiple threads, some E/Z stereo bond modifiers were missing from the output.
Wrong names were generated for structures with multiple attachment points.These cases are now detected and no name is generated for them.Generating a name in this case will be implemented in the future.
Molecule representation
Valence Check Valence Check changed standalone Bi to BiH3.
Valence error was not shown on a Carbon atom having a triple and an aromatic bond. Valence Check accepted Stannane with any number of implicit hydrogens.
Implicit/Explicit Hydrogen Conversion
Stereoinformation was lost during explicit Hydrogen removal from stereocenter when all ligands of the stereocenter were also stereogenic.
Conversion of explicit Hydrogen to implicit one thrown exception when there is only a Hydrogen atom in an R-group definition or in a definition member.
Image I/O
Clean 2D
Clean removed stereo centers around the contracted superatom S-groups.
Clean2D got stuck and error message was thrown for some more complex molecules imported from SMILES.
Stereochemistry
Cis-Trans stereoisomerizm was recognized on flexible Nitrogen atoms.
Stereo information could lost in symmetric bridged systems with explicit Hydrogen atoms.
Calculations
Elemental Analysis
ElementalAnalyser.setMolecule(String) threw exception if the formula contained () brackets (e.g.C6H11N3.2(HCl)).
Protonation (pKa, Major Microspecies, Isoelectric Point)
Minor bug has been fixed on the distribution chart.
Isomers (Tautomers, Stereoisomers)
Stereoisomers plugin failed to generate all stereoisomers for tricyclic compounds.
Generic tautomer generation threw exception on some molecules.
Some invalid 3D structures were not filtered out during stereoisomer generation although 3D-filter option was turned on.
Some cycloolefine stereoisomers were mistakenly filtered out as duplicates, so they were missing from the generated list of stereoisomers.
Structure Checker
In Structure Checker GUI, the scroll bar was missing in the report tab if the report contained four to six structures.
When the Structure Checker configuration contained multiple substructure checkers, their order would change during structure checking process.

Unique SMILES string generation for a fragment could have differed depending on the fragment count of the molecule
Peptide
User defined custom amino acid dictionary caused wrong custom amino acid structure or java.lang.ArrayIndexOutOfBoundsException during peptide import.
Name to Structure (n2s)
When calling a custom name-to-structure webservice, names with special characters (including space) were not URL encoded, possibly resulting in failed conversions for such names.
Name containing fused rings and converted to all uppercase letters were not recognized.
Name to Structure could get stuck in a deadlock during the first usage when that occurred concurrently in several threads.
When using the "name converters" API, converters were not properly removed after using thread-local converters.
Document to Structure (d2s)
When interrupted while doing OCR or OSR, document to structure logged an exception about the interrupt.This caused in particular a warning dialog to appear in Instant JChem during a document import.
Names were not recognized when they contained a complex bracketed bond locant followed by a comma, such as "2(7)" in tricyclo[6.3.1.02,7]dodeca-2(7),3,5-triene.
Scrolling back in MarvinView could have caused failures for very large documents (more than 1000structures) and names with non-ASCII characters.
Structure to Name(s2n)
name:source returned an empty name for empty structures instead of the actual stored name.
The name "perimidine" was not attributed to the right structure.

Initial support for Chinese IUPAC and common names has been added, e.g., 2-??-4-????.
Names with extra closing brackets can be converted when OCR error correction mode is enabled.
Name to structure now also works when bridge and spiro numberings are represented by using unicode superscript numbers, such as: tetracyclo[12.4.0.02,6.07,12]octadecane.
Custom webservice to extend name to structure conversion - for instance using corporate IDs (e.g., ABC0001234) or common name dictionaries in addition to the default one - is supported.
Automatically fix and import spiro names where the superscript formatting has been lost, for instance, after copy-pasting.As an example, trispiro[2.2.2.29.26.23]pentadecane will be imported as if from the correct form, trispiro[2.2.2.29.26.23]pentadecane.
Name to structure now works on names of bridged ring compounds where the superscript formatting of ring numbering is not present.
The custom dictionary can be encoded in UTF-8- even if the system default encoding is not UTF-8- providing a byte order mark (BOM) for the file.This can be used, for instance, to support dictionary in multiple languages on Windows OS.
Document to Structure (d2s)
Invalid hexadecimal character entities (e.g., "&##xblah") are now ignored instead of making the document processing fail.
Image to structure conversion using OSRA is working on Mac OS X.
Text OCR for scanned documents is now supported on Mac OS X.

MarvinSketch Dialog
Focus did not appear on the "Source" and "Import Name" dialogs with Java 7.
Painting
The charge was not displayed in circle on the bracket of an S-group when the "Show charge in circle" was set on the "Preferences" panel.
Charge label masked the adjacent bond in several cases.
Editing
Deleting "extra" explicit hydrogens from an atom with valence error resulted in the appearance of erroneous implicit hydrogens on this atom.
When there were several disconnected structures on the canvas, partial clean was very slow.
It was possible to create a molecule with R-group definition containing a single attachment point (and no other atoms or bonds).
Sprouting did not work for Alias atoms.
The two ways of deleting implicit hydrogens (with eraser directly or selecting them first then deleting) behaved differently.
Load/Save handling in UI
"File > Open" dialog froze when an mrv file contained a dashed arrow and the preview pane was checked.
When opening a multi molecule file and selecting a range that is open ended, a false error message appeared, which stated that there were too many molecules selected to open.
IUPAC name with alpha or beta signs could not be imported.
MarvinViewdid not open when importing a file from command line failed.
It was not possible to append a name to an existing .name file in MarvinSketch.
Clipboard handling
It was not possible to drag a structure from MarvinView in "Translate or Drag" mode.

CXSMILES/CXSMARTS
CXSMARTS I/O lost the charge from generic metal atom.
CDX/CDXML
Reaction agent not having reactant and product (e.g., >CC1=CC=CC=C1>) was read as reactant from CDXML files.
Name to Structure (n2s)
RS - as the marker of racemates - was not converted properly, for instance in (2RS)-1-(Adamantan-1-ylamino)-3-phenoxypropan-2-ol.
Lower CamelCase chemical names (such as 2-cyclopropylPiperazine) were not converted to chemical structures.
Common names, which are also non-chemical names, were recognized as chemical names during automatic format recognition, e.g., "Royal Blue".
E/Z bonds were sometimes set to the opposite value (in cases of non-trivial CIP rules).
For some rare inputs, which are not valid names, n2s created invalid structures that could be exported to mol format but could not be opened.
Both "phenylene" and "phen-1,3-ylene" were wrongly converted to benzene.Now all forms convert to the correct structure with two attachment points, including "m-phenylene", "1,3-phenylene", and "phen-1,3-ylene" (similarly for the o-, p-, 1,2-, and 1,4- forms).
Document to Structure (d2s)
Processing of multiple XML documents in concurrent threads was slow and sometimes skipped some hits.
Names separated by the "non-breaking space" character were not recognized.
Some names split by extra spaces were not found.
English names were not recognized in Japanese documents when the ideographic comma character followed them.
SMILES with aromatic atom after non-aromatic ones ("Cc1...") and with triple(##) or explicit single(-) bonds were not recognized.
Text OCR failed when the images in PDF were encoded in a certain variant of the CMYK color space.
Structure to Name(s2n)
Some characteristic group names were missing when expressed as a prefix of a sulfonyl group, for instance, in "propanamidosulfonyl".
Names could not be generated for structures containing "-[N+]≡" substituent.They are now named using the "azaniumylidyne" IUPAC name component.
Peptide
During automatic format recognition, non-latin characters were recognized as peptide sequences.

Isomers (Tautomers, Stereoisomers)
D, T count in region labels of multifragment generic tautomers was computed incorrectly.
TautomerizationPlugin API did not clean the explicit hydrogens in the result molecule after tautomer generation which might have resulted in wrong stereo (R,S) specifiaction on chiral centers.
Geometry (Topology Analysis, Geometry, ...)
The result of topological polar surface area (TPSA) plugin depended on the call order of setMolecule() and setpH() methods.
cxcalc
Calculation "ringcountofatom" returned only the ring count of atom number zero.
cxcalc returned irrelevant error message for calculations containing "ANY" bonds.
Thole polarizablility (tpol) calculation didn't interrupt when clean3D failed.
Backend / Core
Removing explicit hydrogens on some large PubChem compounds caused infinite loop.

Atom index issue might have occurred when molecule contained explicit hydrogen.
Protonation (pKa, Major Microspecies, Isoelectric Point)
"averagemicrospeciescharge" calculation in cxcalc and "Isoelectric Point" calculation in MarvinSketch threw "ArrayIndexOutOfBoundsException" in the reported cases.
NMR (HNMR, CNMR Prediction, ...)
The calculated chemical shifts of equivalent atoms were not consistent in case of compounds with symmetric ring systems.
Bug fixes:
MView applet
Atom and Bond set coloring was not working properly when Marvin View Applet was called from JavaScript.
Image I/O
When imageImportServiceURL startup option was not set for MarvinSketch, the same setting on the Preferences panel was lost.By default shortcuts and startup scripts do not specify this command line startup option.

Import/Export
Document to Structure (d2s)
Names broken over two lines with a hyphen (-) are now recognized.
Names followed by a superscript text, for instance, a reference or footnote number (e.g., "aspirin11") are now recognized.
Name to Structure (n2s)
In some cases, such as "4-methylthiophenylmethyl", there is an ambiguity whether "thiophenyl" refers to a compound derived from thiophene or thiophenol.Name to Structure now gives priority to the thiophenol related compound interpretation; though, "thiophenyl" by itself will still be supported as thiophene derivatives.
Bug fixes:
Painting
If R-group visibility was turned off and any of the bonds had label(s) to paint, an ArrayIndexOutOfBounds exception was thrown.

Clipboard handling
Java wrapper for CXNSharedAddin library has been introduced to handle tabular data transfer from/to Microsoft Office applications.
Import/Export
CDX/CDXML
Graphical arrows "retrosynthetic" and "equilibrium" are imported from CDX and CDXML files.
Name to Structure (n2s)
Names, such as "methyl ether", are used either to denote a group (CH3-O-*) or the dimethyl ether compound (CH3-O-CH3), as well.The default behavior still is to generate the complete compound, but a new name option "expectGroup" has been added to get the group instead.
A name converter can now prevent a name from being converted (even by other lower-priority converters).See the API of the chemaxon.naming.NameConverter class.
Document to Structure (d2s)
Peptide 3letter abbreviations are now recognized in documents, for instance ValGlySerAla or Val-Gly-Ser-Ala.
A new option has been added to control the maximum time allowed for processing a document: format option "d2s:timeout=60" to allow a maximum of 60seconds.Default is 0meaning infinite timeout.
A new option has been added to disable the extraction of OLE embedded structures from Office documents (option name: "d2s:-ole").
Structures imported from the custom name dictionary now have the "Type" property set to "custom" instead of "common".
Memory usage has been significantly reduced when processing large PDF documents (for instance hundreds of scanned pages).
Structure image conversion by OSRA has become faster, resulting in more structures converted when previously a timeout was reached.
CAS Registry Numbers® (which typically include commas) are not converted by default by d2s anymore (they are still converted by n2s).The old behavior can be activated by using the "d2s:CASnames" format option.
The unwanted interpretation of some common words as chemical names, that are frequent especially in patents, has been avoided.For example, the 'amino' group when used in the phrase 'amino acid', or 'Ser' when it is not the abbreviation of Serine but 'Ser.No.' for 'serial number'.
Structure to Name(s2n)
Multiple name generation tasks can now be run in parallel at full speed to make use of multiple CPUs and cores.
Multiple name import tasks now run faster, as partial locking is no longer required and has been removed.
Generated names now use unicode characters when needed, for instance, 6λ4-thiadispiro[5.2.59.26]hexadecane instead of 6$l^{4}-thiadispiro[5.2.5^{9}.2^{6}]hexadecane.The pure ASCII output can be generated using the "name:ascii" format option.
Image I/O
New parameter imageImportServiceURL has been added to the image importer module.The URL can be set on the "Preferences" dialog or as an import option.
VMN import
VMNs of type "display" are now read.
VMN abbreviated group list has been extended: carbon chains up to 50members have been added.
AV (abnormal valence) property is now stored in atom property and not set as atom valence.The VMN valence representation will be revised in a later version.
Deuterium and tritium count property is handled properly in VMN (added as D and T ligands for non-homology atoms).D and T are transposed during the import in comparison to the VMN, as this represents the correct information in the majority of the MMS database.
Correcting incorrect atom types in VMNs: C0is transformed to CHK; C1is transformed to C; homology groups in ring are transformed to XX
Attachment bond type is set to parent R-atom bond type if different.
VMN import option is available for switching off corrections:
Molecule representation
MolAtom.BRIDGEATOM_H, is added to Hydrogenize.removeHAtoms(MoleculeGraph, int) method to remove hydrogens connected to bridgehead atoms.Valence Check
Local valence check has been introduced, which calculates the valence by considering only the neighboring atoms.Although the new valence check is the default, the old one is also available.
S-groups
ElementalAnalizerPlugin calculates Polymer Formula for molecules containing SRU or RepeatingUnit S-groups.
Calculations
Charge (Charge, Polarizability, ...)
Dipole Moment Calculation plugin: calculates the net molecular polarity.
NMR (CNMR Prediction, HNMR Prediction)
New, mixed HOSE code/CXN model has been introduced, which results in more accurate NMR shift prediction.
C-F and H-F couplings are considered during NMR shift calculation.
Diastereotopic protons are supported in HNMR Prediction.
The tautomers of the predicted molecule are accessible via the Options > Select Tautomers...option of the NMR GUI.The spectra of the selected tautomers with defined percent composition are added to the predicted spectrum.
Chemical Terms
"molString" and "molFormat" Chemical Terms functions are accessible under the name "molConvert" as well.
Structure Checker
Structure Checker is going to be moved to the MarvinBeans package.Until it is done, the new Structure Checker GUI is available in both JChem and MarvinBeans packages as Structure Checker JChem and Structure Checker , respectively.
Substructure Checker feature is accessible only in Structure Checker JChem until the complete relocation of Structure Checker.
Improved R-group Attachment Error Checker detects R-group definitions having incorrect R-group attachment orders.Fixer is not available for this feature yet.
New Explicit Hydrogen Checker options are ready for use.
Checkers that are not recognized as internal or external checker are called: "Invalid Checkers".Invalid Checkers cannot be used in valid Structure Checker configurations; they need to be removed to perform proper working behavior.
Build/Installation
Marvin Beans and JChem installers - for Linux - bundled with Java 1.6.0_33have been introduced.

Name to Structure (n2s)
Names ending with "group", such as: "cyclohexyl group" were not imported.
Chirality specified without locant was sometimes not included in the generated structure, for instance in (R)-tert-butyl 3-aminopyrrolidine-1-carboxylate.
Document to Structure (d2s)
Several names separated by a comma were sometimes wrongly recognized as a single name.
Document to structure was leaking some memory in a way that was problematic for extremely large documents (tens of thousands of structures in a single document).
When using the d2s API, waiting threads could be left behind when large documents were converted but the structures were not read until the end.This is now fixed, provided the client calls MolImporter.close().
Document to structure was not processing text from PDFs with non-standard fonts, for instance English text encoded in Japanese fonts.
Certain images in PDFs were not processed correctly by OSRA during optional image-to-structure conversion.
Names found in documents may have included unwanted trailing characters when the next word started with an open bracket, for instance, "cholesterol [28]" instead of "cholesterol".
Structure to Name(s2n)
The group "[NH3+]-" was given traditional name "aminio", instead of the correct "ammonio".

Aromatic carbon cations having three ligands were handled incorrectly by the Valence check.
False positive valence error was on aromatic rings which have sulfur ligand that is part of a ring.
Removing explicit hydrogen atoms from LiH, CaH2, SH4, PH5, PbH2, PbH4 did not keep the original hydrogen count.
Aromatic carbon cations having three ligands were handled incorrectly by the Valence check.
S-groups
Bracket positioning did not take the implicit hydrogen atoms into account.
If data were added as "relative", the cleaning or arrange methods did not take them along with the fragment/component/molecule.
The chirality of expanded S-group's atom changed, when there wasn't enough space in the canvas for the expanded S-group.
After expanding S-groups, atoms of the molecule could overlap.
Removal of explicit hydrogen being the only atom of an S-group was unsuccessful.New flag, SGROUP_H, has been introduced, for remove such hydrogens.

Aromatic ring count returned zero in cases where the aromatic ring contained negatively charged carbon with two aromatic and one single bond.
Calculations
Protonation (pKa, etc.)
CH acid type structures might have caused errors during pKa calculation.
Isomers (tautomer., reson.)
Wiggly bonds were changed to single bonds during standard canonical tautomer generation.
Resonance structure calculation of nitrogen containing molecules has been reconsidered: 10valence electrons around a nitrogen are only allowed for nitro groups.

CML, MRV
New option to MRV and CML export, :C N , is introduced, where 0< N ≤ 9and N is the length of the decimals of the exported coordinates.For example, mrv:C5
Name to Structure (n2s)
Conversion of systematic names has been increased by about 5%, and increased accuracy of the generated structures.
Prefix "nor" has been implemented (e.g., 17-Hydroxy-19-norpregn-4-ene).
Name with stereo-markers "r" or "s" where such stereoconfiguration cannot be present are now interpreted as "R" or "S".This allows names that have been completely lowercased to be converted correctly.
Document to Structure (d2s)
Document to Structure supports the following common office document formats: doc, docx, ppt, pptx, xls, xls, odt in addition to pdf, xml, html and txt.
Format options have been added to d2s, to specify what input formats should be converted (for CAS Registry Number®, SMILES and InChi).Format option "insideTag=<tag>" to restrict conversions to the content of a specific tag (for instance in HTML).
The type of source text used for the conversion is included in generated structures.Possibly values: systematic, generic, common (for names), smiles, InChI, CAS Registry Numbers® (for text formats), cdx, mrv, symyx (for embedded structures in office documents).
Processing speed has been increased: doubled on typical documents including chemical names, and tripled on documents with few chemical names.

Bug fixes:
MarvinSketch GUI
MarvinView3D window could not be opened from the sketcher if MarvinView 2D window had been opened before.
Applet
Applet settings could influence the client side desktop application settings.
Painting
The query properties were wrongly painted in some cases and covered the atom labels.
3D rotate action activated automatically when joining a structure in hand to a bond of a 2D structure on the canvas.
Double bond was not painted in centered position in case of terminal bonds when the label of the connected atom was displayed or both of the atom labels were displayed.
Single arrow type brackets were not painted.
The orientation of explicit hydrogens was incorrect when explicit hydrogens were added to the (selected) upper methylene C atom of a cyclohexane.
Import/Export
MOL, SDF, RXN, RDF
Handling of special characters (-, ", space) in extended MDL MOL format IO was wrong.
RDF file exported by Instant JChem was not imported correctly to ISIS/Base.
SMILES, SMARTS
In some rare cases, the unique SMILES of a molecule depended on the numbering of the atoms.
CML, MRV
Parity value in CML format was stored the opposite way as the CML standard defines it.Now the correct value is stored which leads to backward inconsistency with CML files generated by Chemaxon applications in previous versions, but correct values are read from standard CML files.To avoid running into similar problems in the future, now a version information is stored both in CML and MRV formats.This information contains a version number of the file format and the application version by which the file was generated.The parity value is changed to opposite in MRV format as well to be consistent with the CML format but it does not lead to backward inconsistency in this case: parity values stored in not versioned MRV files are converted to their opposite while parity values from versioned MRV files are not.
View settings were not applied in exported pdf file.
VMN
VNM format sometimes was recognized wrongly as mol2.
Image I/O
The molecule source was generated in unnecessary cases.
javax.imageio left temp files open if the ImageOutputStream was not closed properly.
Structure to Name (s2n)
The generated names for bridged and spiro ring systems were missing E/Z stereodescriptors for double bonds in large rings.
Some unconventional names were generated with suffixes such as amido, sulfonyl, carbonyl, ...mentioned as prefixes.For instance 2-[(2-chlorophenyl)amido]benzoate for [O-]C(=O)C1=C(NC(=O)C2=C(Cl)C=CC=C2)C=CC=C1.The generated names is now 2-(2-chlorobenzamido)benzoate.

Calculator Plugins
"Marvin Services" has been introduced: Web/local services client, which provides seamless integration of third-party calculations into Marvin Sketch, cxcalc, and via Chemical Terms into Instant JChem or JChem for Excel.Industrial standard solutions like SOAP with WSDL are supported, along with the more lightweight XML-RPC or JSON-RPC protocols.Java based calculations can be called without server, directly from the jar file.
A new type of fragmentation has been implemented where the fragments contained in the same S-group are not separated.Fragmentation methods now have fragmentation type as parameter.The three types of fragmentation are:
Basic: no S-groups are considered, fragments are separated even if they are in one S-group.Broken S-groups are not added to the fragments.
Keeping multicenters: multicenter S-groups are kept in one fragment, other types of S-groups that contain more than one fragment are not added to the fragments, those fragments are separated.
Keeping S-groups: all S-groups are kept, fragments in the same S-group are not separated.
Previous fragmenting methods which did not indicate the type of fragmentation are deprecated; they do the same as before (keep multicenters), but now – correctly – without generating inconsistent molecules with broken S-groups.These methods will be removed in later releases.
Markush enumeration
There is a significant speedup of sequential and random Markush enumerations.(Hundreds of times speedup for average patent Markush structures.Speedup depends on the complexity of Markush structures.)

pKa:
Hydrogen bound defined between aromatic carboxyl and phenolic hidroxyl groups in pKa plugin.
Calculation of the sulphonamid acid molecules were improved.
Molecule file formats:
Extended reaction files: AGENTS are imported and exported (in a non-standard way, because MDL's standard format does not support them).
SMILES import: error checking improved.
PDB import/export: bonds of standard residues are not exported and not guessed from coordinates at import.Full atom names (including remoteness indicator and branch designator) are imported and exported.
2D and 3D:
Background color, rendering style and navigation mode are stored separately for 2D and 3D.Cleaning a molecule in 3D also switches automatically to the 3D parameter set in that cell.Cleaning in 2D switches back to the 2D parameters.
MDL import/export Improvements::
Extended reaction file import/export ("rxn:V3").
Rgroups are supported in extended molfile import/export.

Molfiles:
Sgroups are also imported as (PDB) residues.As a consequence, the PDB-specific coloring styles, "shapely" and "group", are also applicable to molfiles containing Sgroups.
Extended (V3) molfile export.
Changes in V2format:
3D molecule coordinates are stored in Angstrom units.The unit can be specified as an import option.

Molecule.rot(...), tra(...), magnify(...) removed, use transform(CTransform3D T) instead
Atom coordinates became absolute
Molecule.getO() and setO() replaced by getLocation() and setLocation()
Molecule.getCenter() renamed to calcCenter(), and it calculates center of mass instead of geometrical center
New: Molecule.moveTo(location)
CGraph.indexOf changes
Splitted into two methods, indexOf(CNode atom) and indexOf(CEdge bond)
Speed improvement.CNode and CEdge has an index field that contains the object's index in its parent graph.Calling the parent graph's indexOf method returns the value of this field.The index is only searched (in the old way) when the CGraph is not the direct parent.
Valence rules
New: MolAtom.ionChargeOf(Z)
MolAtom.negoxOf(Z, boolean) removed, negOxOf(Z), posOxOf(Z) created instead

CGraph.removeNode and removeEdge instead of remove and removeRef; removeEdge leaves edge.node1and edge.node2unchanged (they were set to null in removeRef).
MolBond.setFlags(int flags, int mask) method introduced.
Stereochemistry: double bonds can also be UP/DOWN (not just CIS/TRANS); CIS and TRANS information can also be stored (not just EITHER).The MolBond.getStereo and setStereo methods and the UP, DOWN, EITHER constants ceased to exists, the STEREO1_UP, STEREO1_DOWN, STEREO1_EITHER, STEREO2_CIS, STEREO2_TRANS, STEREO2_EITHER, STEREO_CARE flags introduced instead.
Structures are colorful by default.Colorization can be disabled by setting colors=mono, both in the sketcher and the viewer.
Spacefill rendering can be enabled instead of wireframe by using the style parameter.
Atom labels can be hidden with the labels parameter.
Up/down and cis/trans either bonds
Classes in chemaxon/beans moved to chemaxon/marvin/beans.The MarvinSketch bean is chemaxon.marvin.beans.MSketchPane, the MarvinView bean is chemaxon.marvin.beans.MViewPane.
The basic applet tag for MSketch and MView is simplified, and also generalized to work with or without Oracle's Java Plugin.
New file format: PDB (for simple, non-macro molecules)
Changes in template handling
The four template sets that come with Marvin became default.Templates only have to be specified as applet parameter if you need a different template set.
Templates moved to directory chemaxon/marvin/templates/ (from templates/).
File extension changed to .t (from .cssdf).
This change was required because of a Netscape restriction related to the loading of JAR file resources.
chemaxon/marvin/templates/generic.t, so the firewall problem ceased for the generic template set.If needed, the additional templates may also be put into the JARs by the user with the JAR utility (part of Oracle's JDK).However, doing this increases the JAR size with a noticable amount.
1. New query bond types: "single or double", "single or aromatic", "double or aromatic", "chain" and "ring".
1. SMARTS export handles the heteroatom (Q in molfile) type intelligently.
1.
The heteroatom and the any atom types are specified in the queryAtoms parameter.The anyatom parameter became deprecated but is still present for backward compatibility, with slightly changed behavior.Specifying anyatom with any value (empty string also) is equivalent to specifying "any,hetero" in queryAtoms.
1. Cell selection in MarvinView can be controlled using the selectable parameter.
1.
New methods in MarvinSketch: getBondlen.getMag, getPiece, getRescaling.New method in MarvinView: setSelectedIndex, The setDispopts method ceased to exist.Display options can be set using the dispopts applet parameter only.
1.
In Marvin 2.2and later, the Java classes come only in packaged forms: marvin.jar and marvin.zip.It means that support is ceased for those archaic Java-compatible browsers that cannot handle the ARCHIVE option in the applet tag (Netscape 2and MS Explorer 3).Reasons:
1.
Under certain circumstances, some Netscape versions try to load the class files one by one instead of using marvin.jar.The simplest way to keep Netscape from doing so is to remove the class files.
1.
Most of our users don't understand what ARCHIVE is, and don't use it properly.The consequence is a significantly increased download time.
From now, a missing ARCHIVE option cannot be left unnoticed, because Marvin will simply not run.Much better than turning your user's hair gray.
1. Marvin is rarely tested in the oldest (and buggiest) browsers.
If you are absolutely sure that you want your Marvin page work with Netscape 2and MS Explorer 3too, you must unpack marvin.zip manually.However, we do not recommend this, because you will probably do something wrong.For example, once you will upgrade Marvin and forget to unpack the new marvin.zip.Mixing two different versions will result in malfunction.
Molecules in MarvinView are only editable if the editable applet parameter is set.
1. CML (XML) export.
1. The getSelectedIndex() method in MarvinView.
1.
Default value of the rescaling parameter in MarvinSketch is changed to "mag" because generally this value is the most useful.
1. The MarvinView-only package ceased to exist, the new Edit/Structure function made it irrelevant.
1.
Templates in MarvinSketch: From now on templates are stored in SDfiles (.sdf) or compressed SDfiles (.cssdf).The template file can be optionally compressed with GZIP, but the applet will only work in Java 1.1compatible browsers in that case.The tmplmol, tmplpar, and ntmpls parameters no longer exist and are replaced by the much more easy to use tmpls parameters.The unit rotation angle can be specified as a new Marvin-specific property M MRV PHI in the template molecule files (instead of the tmplpar parameters).
1. Applet tags changed: Rewrite your applet tags according to the last solution in MarvinSketch Example 1 .This applet tag can load the AWT and the Swing applets as well.
Note that the file &{marvinjar}; is not packaged now (its name caused too many problems), so you must rewrite your applet tags, otherwise the download time with MS Explorer will not be optimal.
1. New in MarvinSketch: The menubar parameter enables or disables the menu bar in the Swing sketcher.
1. New in MarvinView: Molecules start rotating in 3D automatically if you set the animate parameter in MarvinView.
1. New in MarvinView:Border between cells in molecule tables.
1. Change in MarvinView: From now the colors can be specified in the same way as in MarvinSketch.Molecule background is molbg, normal table background is bgcolor.(Previously, bgcolor was also the molecule background.)
1. JavaScripter applet ceased to exist.
Its functionality is moved into a MarvinView module that is automatically loaded at the first js: action.
In the past, JavaScripter was required because scripting applets are not cached by older browsers (namely Netscape 3).An applet that has the MAYSCRIPT attribute is loaded from the net for each page that contains it.In Netscape 4and later, there is no such problem.On the other hand, a bug (or feature?) in Netscape 4.6makes the use of JavaScripter impossible as a separate applet.That's why we merged the two applets now.
1. New: Three new molecule file formats: "sybyl" (the SybylImport and SybylExport modules), "xyz" ( XyzExport ), and "pov" ( PovExport ).
1.
New and changed: The "implicitH" option in the dispopts applet parameter instead of the showH parameter which ceased to exist.
"off" -> "implicitH=off"
"term" -> "implicitH=heteroterm" (because "term" ceased to exist)
"hetero" -> "implicitH=hetero"
"heteroterm" -> "implicitH=heteroterm" (default)
"all" -> "implicitH=all"
New features: if you want the explicit H atoms to be invisible, use "explicitH=off" (default: "all").
If you have 3D molecules, use "dim=3" for MarvinView, to let him know that you want 3D rotation as the default mouse drag action.
1. New: The atomStrings parameter enables the usage of atom aliases and SMARTS strings in the sketcher.
1.
Incompatible change: The setAtoms, setNoatoms, setNobonds methods, and the atoms, noatoms, nobonds applet parameters ceased to exist and replaced by elements , anyatom, queryAtoms , and extraBonds .
1. New: The new detach parameter makes it possible to detach the sketcher from the web page immediately when the applet is loaded.
1. Recommended: In molfiles and compressed molfiles written directly in HTML, you should end all the molfile lines with backslash and also a real newline character like here:
...
000Wun+V70\
iuzV000W60\
iuzVGS2W60\
K72WGS2W60\
...Omitting the real newlines like in "000Wun+V70\iuzV000W60\iuzVGS2W60\K72WGS2W60\", seemed to be safe so far, while the Marvin applets were tested only in Oracle, Netscape, Symantec, and Microsoft JVM's.The reason for discontinuing this practice is that the AppletViewer in Kaffe 1.0b3has problems if you write more than one molfile lines in one HTML line.
1.
Removed: Backward compatibility with the old style (1.0-1.1) usage of getMol() and getM() removed.It didn't work with MSIE anyway.
1. Incompatible change: MSketch.getMol(x) and MView.getM(n,x).
In Marvin 1.1.4and before, x was a boolean variable specifying the format of the generated molfile: MDL mol (false) or compressed mol (true).
From version 1.2, x is a format descriptor string to ease the introduction of new molecule file formats as Marvin evolves.MDL molfile format is denoted by the string "mol", compressed mol is "csmol", SMILES is "smiles".
1. New: The preload applet parameter.
"Extra features" are planned to be available as external modules in future releases of Marvin.External modules are downloaded only when needed.In Marvin 1.2.3, MDL mol, compressed mol and SMILES export are external modules.
The problem is that older browsers such as Netscape 3, cannot load the external modules when the module is needed by a public method which is called from JavaScript.So if you want your web page containing Marvin to work perfectly with earlier releases of Netscape than 4, then you should preload all the modules which may be needed by JavaScript calls.
For example, if you are using MSketch.getMol("smiles") on your page, then you should also have the following applet parameter:
<param NAME="preload" VALUE="SmilesExport">.
