[Rdkit-discuss] Pharmacophore matching

2023-06-20 Thread Hilleke Mattis
Dear all, I am new to working with the Pharm3D module and I have a question regarding pharmacophore matching: Is it possible to match a molecule to a pharmacophore that requires one atom to match to two different features (e.g. H-bond acceptor and donor)? Here is a dummy code example for a case

Hi, I have a related question: how to output the type of an atom in a molecule, if possible in a human-readable format; i.e. a human readable/understandable string rather than some (obscure) integer. I am interested to look at the atom types used by the ECFP and the FCFP fingerprints. Thanks a

Hi Lewis, This is a great chance to demonstrate some of the things that can be done with the new fingerprint generation code. It's going to take me a bit to put this together (it's all new enough that I'm still not quite "fluent"), but I will try to get an example put together over the next couple
