bool OEPerceiveChiral(OEMolBase &)

Perceives whether an atom or a bond in a molecule is chiral and updates the ‘chiral’ property accordingly. Because this function is based on the symmetry classes of a molecule, as a side-effect, it also sets the ‘symmetry’ property of all the atoms the molecule to be their ‘explicit hydrogen suppressed’ symmetry class, by calling the OEChem TK function OEPerceiveSymmetry.
