Dear phenix.bb How do I specifically exclude particular amino acids from torsion-angle ncs?
From the GUI, it is not obvious.
In a couple of my chains, one or two amino acids are in definite crystal contacts, and are therefore in a different rotamer/conformation compared to the other ncs-related copies. Unfortunately, I can't seem to find the right option / keyword to stop the refinement job moving these side-chains to agree with the rotamers found in the other molecules of the asymmetric unit.
