    Deprecated. As of Marvin 6.1,
    Usage:
    In the specified methods the CIS|TRANS or CIS|TRANS|CTUNSPEC values are used instead.
    CIS/TRANS cannot be determined because bond angle is close to 180 degrees. This is not a flag in MolBond. This corresponds to CIS|TRANS (double bond) or CIS|TRANS|CTUNSPEC (C/T? double bond)

    OR stereo group type for enhanced stereo representation. Must be used together with a number, eg. OR1, OR2, etc. This group type represents a pure sample of stereoisomers with the labelled chiral centre as drawn or in the opposite stereo configuration, however the relative stereo configuration of the same group must not change.
