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?
