SetAtomPredicate
bool SetAtomPredicate(const OESystem::OEUnaryPredicate<OEChem::OEAtomBase>&)
Provides an input atom predicate to define the selection of the atom stereocenters which should be enumerated.
SetBondPredicate
bool SetBondPredicate(const OESystem::OEUnaryPredicate<OEChem::OEBondBase>&)
Provides an input bond predicate to define the selection of the bond stereocenters which should be enumerated.
SetEnhancedStereo
bool SetEnhancedStereo(const bool)
Sets whether to consider explicit MDL enhanced stereogroups during flipping. Enhanced stereogroups generally contain a collection of stereocenters which should be considered as a collective unit, where a “flip” implies that all centers in the group should be flipped, thus retaining the relative stereo parity between the grouped stereocenters. With this flag enabled, far fewer enantiomers will be generated than for individual stereocenter flipping activities, and relative stereo configurations will be retained. When enabled, explicitly marked absolute stereocenters are excluded from the flipping activities. Care should be taken to ensure that any custom atom predicate returns all atoms involved in enhanced stereogroups. Default: False
Note
The membership and type of existing enhanced stereogroups are not modified as a result of the flipping operation.
That is, the explicit stereogroups of and and or are not promoted to abs groups as a result of stereocenter parity flips.
This retains the source of original stereogroup(s) in the generated isomer(s) for post-flipping validations and processing.
This behavior is true regardless of the setting of GetEnhancedStereo.
Stereocenters can be explicitly promoted to abs centers by deletion of all stereogroups, or by deleting all stereogroups and
adding marked stereocenters to a single new abs stereogroup.

SetEnumAtoms
bool SetEnumAtoms(const bool)
Sets whether to include R/S stereocenters in the enumeration or not. If false, disregards atom enumerations. Default: True
SetEnumAtomSpecifiedStereo
bool SetEnumAtomSpecifiedStereo(const bool)
Sets whether to force the modification of all R/S stereocenters in a molecule. If false, it will only enumerate stereocenters which do not already have a specified stereochemistry. Default: False
SetEnumBonds
bool SetEnumBonds(const bool)
Sets whether to include E/Z bonds in the enumeration. If false, disregards bond enumerations. Default: True
SetEnumBondSpecifiedStereo
bool SetEnumBondSpecifiedStereo(const bool)
Sets whether to force the modification of all E/Z stereocenters in a molecule. If false, it will only enumerate bonds which do not already have a specified stereochemistry. Default: False
SetEnumBridgehead
bool SetEnumBridgehead(const bool)
Sets whether to enumerate bridgehead stereocenters. Default: False
SetEnumEZ
bool SetEnumEZ(const bool)
Sets whether to enumerate E/Z stereocenters. Default: True
SetEnumNitrogen
bool SetEnumNitrogen(const bool)
Controls the behavior with respect to the enumeration of nonterminal nitrogens. Any nitrogen with pyramidal geometry in the initial model of the input molecule, and having no more than two ring bonds, is considered to be invertible. This will enumerate all possible puckers if set to true. Default: False
SetEnumRS
bool SetEnumRS(const bool)
Sets whether to enumerate R/S stereocenters. Default: True
SetEnumRelativeAtomStereo
bool SetEnumRelativeAtomStereo(const bool)
Sets whether to include enumeration of internally perceived relative atom stereocenters (e.g., 1,4-disubstituted cyclohexanes) in a molecule. If true, consider relative stereocenters during stereo enumeration. Default: False
SetEnumSpecifiedStereo
bool SetEnumSpecifiedStereo(const bool)
Sets whether to force the modification of all of the atom and bond stereocenters in a molecule. If false, it will only enumerate stereocenters which do not already have a specified stereochemistry. Default: False
SetMaxCenters
bool SetMaxCenters(const unsigned)
Sets the maximum number of stereocenters or groups of stereocenters which will be fully enumerated. Default: 12
SetWarts
bool SetWarts(const bool)
Sets whether to generate unique titles for molecules. Default: False
