Hi Daniel, this is some oddity that happens with molecules constructed from InChIs. CalcNumAtomStereoCenters() returns sensible results if you call it on the molecules constructed from SMILES: In [24]: mol_list2 = [Chem.MolFromSmiles(Chem.MolToSmiles(mol,True)) for mol in mol_list] In [25]:

Hi All, I have a list of compounds (InChi strings) that I need to filter. Basically I need to identify which molecules are missing stereo information. I came across the "CalcNumUnspecifiedAtomStereoCenters" which sounded exactly like what I needed, but unfortunately all it does it return 0s,
