WebFeb 28, 2024 · So, in RDKit, if you convert smiles_1a to mol and this mol back to SMILES again, you get c1ccc2c (c1)-c1cccc3cccc-2c13. If you search with this, you will still not find structures 3 and 5. Probably because of the defined single bonds. However, if you replace - by ~, you get smiles_1b: c1ccc2c (c1)~c1cccc3cccc~2c13. east carolina physicians greenville nc

WebMar 17, 2024 · Hi Baptiste, RDKit focuses on "simple rings". As far as I know, it has no builtin function to return all possible cycles in a molecule. For a molecule with a "basis set" of N rings, there can be up to 2^N-1 ring systems, which can be obtained by taking all possible subsets (aka the powerset) of rings and fusing them. 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.
