Dear all, Is it possible to limit Ramachandran restrain to specified residues in phenix.refine? I have a couple of loops with very poor density. The refinement process always made some residues fall out of ramachandran plot no matter how I tightened the weight and adjusted the residues back. Because the diffraction is about 2.3 A, I don't want the ramachandran restrain to impact the rest of structure. Thanks. Nian Huang
