WebMay 1, 2024 · get_smiles() follows the general pattern for rdkit-cffi functions which operate on molecules: the first two arguments are the pickled molecule and the length of the pickle string, the third argument is a JSON string with additional options to be used when generating the SMILES; in this case we want the defaults, so we pass a NULL pointer (we ... 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.
