WebOct 21, 2016 · Substructure search and fused rings. I'm using the RDKit Molecule Substructure Filter to filter molecules using small fragments (generated with the MoSS node) as queries. Everything works as desired 95% of the time but in certain cases the query is identified inside a fused ring (e.g. piridine found in a quinoline) which I would like to avoid. WebMar 1, 2024 · In RdKit, the method SetProp is used to set an atomic property for the atoms involved in the molecule. This method takes two arguments: the peroperty to set and its value. The idea is simple: Create an rdkit mol object from SMILES string, iterate over the atoms, and set the desired property to a custom value.
