WebApr 3, 2024 · Hi, I’d like to generate a set of conformers with restraints on some of the substructures. I’d like to keep one segment of the molecule frozen, allowing the rest of the molecule to be mobile. Within the part of the molecule that is mobile, I’d like to restrict the torsion angles for one of the substructures. How can I go about doing this? WebIn this code snippet I just use an added torsion constraint with a very high force constant to get certain dihedral angle. It works well in version "2024.03.3" but gives very bad results in "2024.09.1". Starting with the attached MOL file, rdkit version "2024.03.3" gives the top result, while version "2024.09.1" gives the bottom version:
