WebJun 24, 2024 · Pose clustering is based on in place RMS calculation of the molecule poses. However, RDKIT cannot perform in place RMS calculations (yet). Because of that I will need to use another library (for instance Pymol) or calculate the RMS by applying the RMS formula ( wikipedia_RMSD ). For this workflow, I will use both and then I will discuss … WebMar 11, 2024 · Try the k-Medoids node. This should work pretty well. Use the RDKit Fingerprint node to generate the FPs (Morgan for instance), then use the Distance Matrix Calculate node to generate a Distance Matrix. Now connect this to the k-Medoids node, and specify how many clusters you would like. The cluster centre (Medoid) is reported also.
