Hi,
What exactly does phenix.real_space_refine do with the mandatory "resolution=" keyword when refining a model against a ccp4/mrc formatted map?
Is this purely for adjusting restraints etc, or does phenix internally low-pass filter or resample the map based on this parameter?
This seems like a basic question, so I apologize if the answer is staring me in the face, but I couldn't see it in the online documentation or in the output of phenix.real_space_refine --help.
