Detailed Description

A writer for molecular graph data in the MDL Mol-File [CTFILE] format.

MOLMolecularGraphWriter supports the following control-parameters:

Control-ParameterDefault Value (see Chem.ControlParameterDefault)Description
Chem.ControlParameter.COORDINATES_DIMENSION0Specifies the dimension of atom coordinates
Chem.ControlParameter.STRICT_ERROR_CHECKINGFalseSpecifies whether non-fatal recoverable errors should be ignored or cause a write operation to fail
Chem.ControlParameter.BOND_MEMBER_SWAP_STEREO_FIXTrueSpecifies whether reverse stereo bonds shall be converted to regular stereo bonds by swapping bond start and end atoms
Chem.ControlParameter.MULTI_CONF_EXPORTTrueSpecifies whether to write all molecule conformations on output
Chem.ControlParameter.MDL_CTAB_VERSION0Specifies the desired connection table format
Chem.ControlParameter.MDL_IGNORE_PARITYTrueSpecifies whether the stereo parity of atoms shall be ignored
Chem.ControlParameter.MDL_UPDATE_TIMESTAMPFalseSpecifies whether the timestamp of Mol- and Rxn-File header blocks has to be updated
Chem.ControlParameter.MDL_TRIM_STRINGSTrueSpecifies whether to remove leading and trailing whitespace from string values
Chem.ControlParameter.MDL_TRIM_LINESFalseSpecifies whether to remove leading and trailing whitespace from data lines
Chem.ControlParameter.MDL_TRUNCATE_STRINGSFalseSpecifies whether string values that exceed the size of an output data field may be truncated
Chem.ControlParameter.MDL_TRUNCATE_LINESFalseSpecifies whether data lines that exceed the maximum allowed line length may be truncated
Chem.ControlParameter.MDL_IGNORE_LINE_LENGTH_LIMITTrueSpecifies whether to check if data lines exceed the maximum allowed line length
