http://rdkit.org/docs/Overview.html WebSep 1, 2024 · By default, the RDKit applies its own model of aromaticity (explained in the RDKit Theory Book) when it reads in molecules. It is, however, fairly easy to override this and use your own aromaticity model. The easiest way to do this is it provide the molecules as SMILES with the aromaticity set as you would prefer to have it.
