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 (). jc sandinWebRing 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. Many chemistry toolkits, though not all, implement a ring finding algorithm which identifies the most chemically relevant rings. kyona trademark lawyerWebSep 1, 2024 · The RDKit implementation picks the atom with the smallest Morgan invariant. This way the choice is independent of the atom order in the molecule. In the case of symmetric atoms a and/or d, the RDKit implementation stores all possible torsional angles in the TF instead of only storing the smallest one as in the original approach. jc sampa nomeWebApr 12, 2024 · Key Takeaways.
