      • Sequences (even if they contain expanded residues) are aligned into a horizontal line and are broken into multiple lines after 20 residues. Each line is read from left to right.
      • Space is left for chemical parts connected to the third attachment of the residues, these attachments are aligned to the top of the residue. Attachments to expanded residues are also considered.
      • Chemical parts connected to the beginning and the end of the sequence are aligned to the left and to the right of the sequence.
      • Chains of sequences connected with chemical linkers are also handled: chemical linkers are aligned horizontally to the sequences to which they are connected and space is left for them between the lines of the sequences.
    • Default 2-dimensional clean of bicyclic molecules has been changed. The old behaviour can be switched back by selecting 'Bicyclics' on the Template Library GUI (Insert<Template) then ticking the 'Use molecules as template at 2D cleaning' option on the 'Properties' page.
  • Import/Export

    • Picture format 'ppm' is not supported anymore.
    • New tag introduced in MRV file to store the atom properties of the abbreviation even if the Superatom S-group is expanded. Until now such properties were lost.
    • Default handling of bond lengths in the import of MDL formats has changed: bond lengths are rescaled to ChemAxon standard for 2D molecules not only for V2000 format input but also for V3000.
    • Character '.' which is the delimiter between atom property keys and values in CXMSMILES format is escaped, which allows the usage of '.' characters in property keys and values.
    • InChi improvement: import and export of axial chirality and not specified double bond stereo are now possible.

  • 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. Documentation

      • PDF document pages with images in the JBIG2 format 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.

      • 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".

      • 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.

Bugfixes

  • Painting
    • If R-group visibility was turned off and any of the bonds had label(s) to paint, an ArrayIndexOutOfBounds exception was thrown.
  • Image I/O

New features and improvements

  • Import/Export
    • Document to Structure (d2s)
      • Startup time of document to structure has been significantly reduced. This is especially important when processing very short text documents, such as a single sentence or paragraph. The speedup in such cases can be up to 10 times faster.

Bugfixes

  • Calculations
    • NMR (HNMR, CNMR Prediction, ...)
      • NMR Prediction did not use the mixed prediction algorithm, so NMR shift predictions were less accurate.

  • Data transfer
    • 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 3 letter 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 60 seconds. Default is 0 meaning 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).

      • CAS names (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 abbreviated group list has been extended: carbon chains up to 50 members 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: C0 is transformed to CHK; C1 is 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: Documentation
  • Molecule Representation
    • New option, MolAtom.BRIDGEATOM_H, is added to Hydrogenize.removeHAtoms(MoleculeGraph, int) method to remove hydrogens connected to bridgehead atoms.
    • Valence Check

      • 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. Documentation
    • Chemical Terms
      • "molString" and "molFormat" Chemical Terms functions are accessible under the name "molConvert" as well.
  • Structure Checker
    • New Structure Checker GUI has been introduced. Besides the redesigned GUI, new features are also available:
      • Profile management;
      • Filters in Report view.
      Documentation
    • 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.

    • 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. Documentation
    • 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_33 have been introduced.

      • 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).

      • 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, SMILES and inchi). Format option "insideTag=<tag>" to restrict conversions to the content of a specific tag (for instance in HTML).

    • 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.
    • PDF
      • View settings were not applied in exported pdf file.
    • VMN
      • VNM format sometimes was recognized wrongly as mol2.

    • Standalone mode of OLE can be set on the preferences dialog if the application is launched in administrator mode.
  • Import/Export
    • Molconvert has a new option, :D, which is important if the molecule has parity information and has 0 dimension. By default during the export, a clean method is invoked on the structure and the generated coordinates and wedge information are exported into MRV format but NOT the parity information. However, using this option coordinates and wedge information are not generated but parity information is exported.
    • Mrv files can be validated by using the XSD schema containing the description of the mrv format.
    • Export options of cml and mrv formats can be used in molconverter application.

August 31st, 2011: Marvin 5.6.0

New features and improvements

  • MarvinSketch GUI
    • New mouse cursors have been introduced.
    • New structure templates have been added (Alpha D sugars, Beta D sugars, Deoxynucleosides, Flavonoids, Nucleobases, Nucleosides, Protoalkaloids, True Alkaloids, Vitamins, Functional Groups).
  • MarvinView GUI
    • Atoms can be marked in Marvin View by hovering the cursor over it. This also works even if another atom has already been selected. A property change event is sent on every atom mark (Documentation).
  • Applet
  • Import/Export
    • Str2Name
      • New option has been added to generate all common names for a structure, e.g.: molconvert "name:common,all" -s viagra.
      • Less brackets are generated in names in traditional mode. For instance, instead of "{1-[(tert-butoxy)carbonyl]-1H-indol-2-yl}boronic acid" the generated traditional name is now "1-(tert-butoxycarbonyl)indol-2-ylboronic acid".
    • Name2Str
      • MolImporter can now process a PDF file as input and convert the chemical names in the text into structures. Structure images are also converted if OSRA is installed on the computer.
      • Increased support for name to structure conversion (measured between 6% and 30% on certain datasets).
  • 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.)
  • Structure Checker
    • New checkers are available:
      • Unbalanced Reaction Checker: reports if there is difference in the total number of atoms or atom types on the two sides of the reaction arrow.
      • Atom Query Property Checker: detects atoms having query properties. A new fixer can remove the identified query properties.
    • New feature: "3D checker" detected issues can be fixed by "Remove Z-Coordinate Fixer". It flattens molecules by setting the z-coordinates of atoms to zero.
    • Structure Checker command line application has greatly improved. See the documentation for details.
    • Improvements in substructure checker: multifragment molecule handling, implicit hydrogen handling, improved command line access. "Transform" fixer for substructure errors: modifies substructures.
  • API
    • New function to get the enantiomer of a molecule has been implemented: chemaxon.calculations.stereo.Stereochemistry.getEnantiomer(MoleculeGraph m).
    • Applet API has been improved with validateMoleculeStr(String str) and validateMoleculeStr(String str, String format) methods.

    • Deprecation:
      • Use the atomSet applet parameter instead of set, atomSetColor instead of setColor and the MView.setAtomSetColor() and MarvinPane.setBondSetColor() methods instead of setSetColor.

  • 3D:
    • Analitic gradients implemented in Dreiding forcefield for optimization and Clean 3D
  • Document editing with graphics objects in sketcher
    • The MDocument class stores the molecule and other graphics objects like polylines and rectangles. The document can be saved in Marvin Document format.

  • 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.

March 20, 2000: Marvin 2.3.1

The basic applet tag for MSketch and MView is simplified, and also generalized to work with or without Oracle's Java Plugin.

March 4, 2000: Marvin 2.3

  • 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.
    • The JAR files marvin.jar and jmarvin.jar contain 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.
  • The MolImport module moved into marvin.jar because of the firewall problem.

January 15, 2000: Marvin 2.2

  1. New query bond types: "single or double", "single or aromatic", "double or aromatic", "chain" and "ring".
  2. SMARTS export handles the heteroatom (Q in molfile) type intelligently.
  3. 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.
  4. Cell selection in MarvinView can be controlled using the selectable parameter.
  5. 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.
  6. In Marvin 2.2 and 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 2 and 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.
    2. 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.
    3. Marvin is rarely tested in the oldest (and buggiest) browsers.

    If you are absolutely sure that you want your Marvin page work with Netscape 2 and MS Explorer 3 too, 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.

October 4, 1999: Marvin 2.1.5:

Molecules in MarvinView are only editable if the editable applet parameter is set.

September 14, 1999: Marvin 2.1.1

  • getCellCount() method in MarvinView.
  • The anchor parameter in the layout also sets label alignment.

September 2, 1999: Marvin 2.1

  1. CML (XML) export.
  2. The getSelectedIndex() method in MarvinView.
  3. Default value of the rescaling parameter in MarvinSketch is changed to "mag" because generally this value is the most useful.
  4. The MarvinView-only package ceased to exist, the new Edit/Structure function made it irrelevant.

July 20, 1999: Marvin 2.0

  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 1.1 compatible 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).
  2. 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.
  3. New in MarvinSketch: The menubar parameter enables or disables the menu bar in the Swing sketcher.
  4. New in MarvinView: Molecules start rotating in 3D automatically if you set the animate parameter in MarvinView.
  5. New in MarvinView:Border between cells in molecule tables.
  6. 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.)
  7. 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 4 and later, there is no such problem. On the other hand, a bug (or feature?) in Netscape 4.6 makes the use of JavaScripter impossible as a separate applet. That's why we merged the two applets now.
  8. New: Three new molecule file formats: "sybyl" (the SybylImport and SybylExport modules), "xyz" (XyzExport), and "pov" (PovExport).
  9. 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.

January 4, 1999: Marvin 1.3

  1. New: The atomStrings parameter enables the usage of atom aliases and SMARTS strings in the sketcher.
  2. 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.
  3. New: The new detach parameter makes it possible to detach the sketcher from the web page immediately when the applet is loaded.
  4. 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 1.0b3 has problems if you write more than one molfile lines in one HTML line.
  5. Removed: Backward compatibility with the old style (1.0-1.1) usage of getMol() and getM() removed. It didn't work with MSIE anyway.

November 29, 1998: Marvin 1.2

    1. Incompatible change: MSketch.getMol(x) and MView.getM(n,x).

      In Marvin 1.1.4 and 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".

    2. 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">.
