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 ( ~ ).

WebOct 19, 2024 · The PCBA result demonstrates that on a set of over 400,000 SMILES pulled from a public-domain bioassay set, ChemCore on average performs better than RDKit at parsing SMILES by a wide margin. Whatever the reason for ChemCore's better performance, the effect was observed in data sets of different composition and size. WebSep 1, 2024 · This is the approach taken in the RDKit. Instead of using patterns to match known aromatic systems, the aromaticity perception code in the RDKit uses a set of rules. The rules are relatively straightforward. Aromaticity is a property of atoms and bonds in rings. An aromatic bond must be between aromatic atoms, but a bond between aromatic …
