ParameterMeaningDefault
escapeCharEscape character to use for parsing the value of the mol parameter.
abbrevgroupsReplacing the built-in abbreviated group collection with a custom one. The parameter value is the location of the file containing the custom abbreviated groups. chemaxon/marvin /templates /default.abbrevgroup
autoCheckStructure

Enables (true) or disables (false) automatic structure check. To take effect, set statusBar parameter to true as well.

 false
customAbbrevgroupsYou can add further abbreviations for the default.abbrevgroup contents with the contets of the files that can be specified with the help of this parameter. The parameter has to contain the path of the file relatively to the codebase.
It is possible to define more than one file, the separator character can be a comma(,) or a pipe(|) character.

abbrevgroupsAllowedEnables/disables the usage of abbreviated groups. If the function is disabled, typing with the keyboard over the canvas will only allow changing atom and bond types.true
 automaticReactionEnabled
Specifies whether the plus signs should be automatically generated for reactions. If true, plus signs are automatically generated if there is only one arrow (single-step reaction) on the canvas between the unconnected fragments on each side of the reaction.
true
 userAbbrevGroupsAllowed
Enables/disables the usage of user defined abbreviated groups.true
defaultSaveFormatSets the default chemical file format in the Save As dialog.mrv
debugDebug mode. Possible values: 0, 1, 2.0
 menuconfig
Specifies an alternative menu customization file location instead of the default .chemaxon/{MarvinSketch_version}/customization.xml (Unix) or chemaxon/{MarvinSketch_version}/customziation.xml (Windows) file under the user's home. Please note that if this parameter is used, the customizationEnabled parameter is automatically set to false.
mergedstMerge distance of atoms in C-C bond length units.0.1
molFormatDefault file format: mol, csmol, smiles, cxsmiles, cml, pdb, pov, sybyl, or xyz.mol
shortcutsSpecifies an alternative shortcut customization file location instead of the default .chemaxon/{MarvinSketch_version}/shortcuts.xml (Unix) or chemaxon/{MarvinSketch_version}/shortcuts.xml (Windows) file under the user's home. Please note that if this parameter is used, the customizationEnabled parameter is defaults to false.
symbolsComma-separated list of symbols that will be always shown in the Insert Symbol popup. The symbols must be specified as font family name/Unicode code point pairs:  fontname:codepoint . Fonts can be physical or logical. The logical fonts supported by the JRE: Serif, SansSerif, Monospaced, Dialog, and DialogInput.
Example (Δ,?): "SansSerif:U+0394,SanSerif:U+212B"

toolbarFloatableSetting this parameter to false makes the toolbars immovable.true
undoMaximum number of undo operations.50
viewHelpMarvinView help contents.

defaultDatatransferPolicySet this to true if you want to disable the search of datatransfer.properties in the codebase, and use the default configuration (mostly suitable for every use case).false
defaultToolSets the initial editing mode in the sketcher.
