Hi Greg, I am trying to reproduce some machine learning scripts using https://github.com/rdkit/rdkit/blob/master/Docs/Book/data/solubility.test.sdf https://github.com/rdkit/rdkit/blob/master/Docs/Book/data/solubility.train.sdf What is the source of these data? How are they organized? Any

Thanks a lot! I've learnt two messages: 1. I agree GetBestRMS() is the right tool to compare conformers of the same structure 2. O3A is good for aligning different structures(or structures with different topology). However not only the O3A.Align() rmsd value should be check, the Score should be

Hi Zhenting, if you compare different conformers of the same structure you won't need O3A at all, as the atom-atom correspondences will be 1:1, as all conformers share the same topology; GetBestRMS() is all you need. O3A is useful when you need to align molecules which have different

Hi Zhenting, O3A.Align() returns the RMSD between the atom pairs that the O3A algorithm was able to match across the two molecules. O3A.Score() returns the score for an alignment. The score is directly proportional to: * the number of atom pairs that could be matched across the two

Hi Greg, I am learning Open3D ALIGN example code: pyO3A = rdMolAlign.GetO3A(mol2py, mol1) pyO3A.Align() Questions - what is the meaning of the value from O3A.Align() - is that similar to atom wise RMSD? - - what is the meaning of the value from O3A.Score()
