WebSep 22, 2015 · MQN12 according to the original publication is number of heavy atoms and footnote says heavy atoms = All non-H atoms. If I run below code, I get an MQN12 of 0 instead of 4. from rdkit import Chem m = Chem.MolFromSmiles('CCCC') from rdkit.Chem import rdMolDescriptors mqn = rdMolDescriptors.MQNs_(m) mqn[11] # MQN12 = hac = … WebDec 21, 2009 · If you actually want the number of non-hydrogen atoms, you need to loop over the atoms in the molecule and check the atomic numbers. The handling of Hs in the RDKit is, in general, a wart. As long as one sticks to the "standard" workflow (working primarily with hydrogen-suppressed graphs) things are fine, but if the molecules have Hs …
