integer*4 atom
## DescriptionFinds the symmetry order, a canonical ordering of the atoms in the same symmetry class for the given atom. This will cause the values to be calculated if they haven't been already. The molecule must be in the modify-off state.The flag 'iso' controls whether the isomeric or unique SMILES is used. If 'iso' is TRUE, the symmetry order is found for the isomeric SMILES, otherwise, the symmetry order is found for the unique SMILES. ## Return ValueReturns the symmetry order of the atom. For all other objects, this property is defined as -1.## Related Topicsdt_chiclass(3) dt_chiorder(3) dt_chiperm(3) dt_chiseq(3) dt_chival(3) dt_setchival(3) dt_symclass(3) |
