Dear phenix users.

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.

Thanks so much.
