bool OE3DToInternalStereo(OEMolBase &mol)
Assigns the stereochemistry of molecule from its 3D coordinates. It
perceives both the tetrahedral chirality around atomic centers, and
the EZ chirality around double bonds. This function is equivalent to
the sequence OEPerceiveChiral(mol)
followed by both
OE3DToAtomStereo(mol)
and OE3DToBondStereo(mol)
.
