[ phenix dev-568 ] TIL using phenix.model_vs_data, if the "REMARK 3" records in .pdb are adjusted e.g. to set a resolution limit, e.g REMARK 3 RESOLUTION RANGE HIGH (ANGSTROMS) : [change to whatever high resolution limit] REMARK 3 RESOLUTION RANGE LOW (ANGSTROMS) : 42.511 phenix.model_vs_data will pick this up and compute the R-factors for that range.
