I agree somewhat with Lawrence.  I routinely use water_peak.input in CNS, 
since it screens the neighboring atoms, and updates the molecular structure 
file.  Then I can reset the occupancy to zero for a water position that I 
don't like, generate maps, etc. before regenerating the molecular structure 
file.  I always look through the water positions that it's chosen to see if 
it's a disordered sidegroup.

I also like to look at the top set of peaks in the difference map.  Typically 
it will help me identify disordered regions of the structure.
