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
