Whatever the reason for ChemCore's better performance, the effect was observed in data sets of different composition and size.

WebSince, we did not explicitly designate a bond between the two atoms RDKit assumed we dont care if the bond is a single bond ( -) OR (,) an aromatic bond (: ), hence the characters between our atoms. Bond types can also be searched with characters for single ( - ), double ( = ), triple ( # ), aromatic (: ), ring bond ( @ ), or any ( ~ ). WebRDKit Documentation, Release 2012.12.1 displays a message like: [12:18:01] Explicit valence for atom # 1 O greater than permitted and >>> m2=Chem.MolFromSmiles(’c1cc1’) displays something like: [12:20:41] Can’t kekulize mol.
