WebThe "glove effect" in the chiral pockets was proposed to explain the correlations between the steric effect of functional groups and performance of FHMOFs. Moreover, the neighborhood component analysis and RDkit/MACCS MFs show the highest predictive effect on enantioselectivities among the 4 ML classification algorithms with 9 MFs that were tested. WebAug 14, 2016 · To fragment in RDKit use FragmentOnBonds().) Parity of a permutation There's no way from Python to go in and change the permutation order of RDKit's bond list for an atom. Instead, I need to detect if the permutation order has changed, and if so, un-invert the atom's chirality.
