Dear Phenix community, I would like to have some additional information regarding fix_rotamers. In particular : - How Phenix chooses which rotamers need to be fixed ? - Does Phenix really re-calculate the three maps after correcting each rotamer ? For very large structures this is very time-consuming and one can settle for calculating a new map every 10-20 residues. Perhaps this could be a user-controlled parameter ? -Can you please explain how fix_rotamers works together with ncs restraints ? Thank you in advance for shedding light on this, Peter
