<p>Dear phenix users.</p><p>I have a question regarding use of phenix.refine.
We recently moved from Refmac to Phenix and found out that residues with
occupancy 0.00 were refined by phenix.refine, whereas those residues set to q=0
in Coot were not refined in Refmac. How can we avoid refinement of those
residue in phenix? During the refinement is quite convinient to keep residue
with q=0, which can be included in the refinement upon map
improvement.</p><p><br />Thanks so much.</p><p></p><p>Jose M Casasnovas</p><br />
