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.
