WebMay 2, 2024 · Hi Lukas, in the RDKit notation all atoms are explicit if they are present in the molecule graph, including hydrogens. You mention that hydrogens are explicitly present in your input structure, so that's the expected behaviour. If you wish to retrieve the number of heavy atoms you can use mol.GetNumHeavyAtoms ().
WebRing counts can be used as descriptors and as ways to classify structures. One way to compute the ring count is to compute the Euler characteristic: #Rings = #Bonds - #Atoms + #Components.
