R factors as a function of resolution d _PDB on a logarithmic scale. The curves show the minimal (blue), average (green), maximal (violet) and mode (red) values; the mode is calculated in the intervals containing a high enough number of models. The thin lines show the corridors around the mode. Each corridor contains 40% (black), 60% (brown) and 80% (dark green) of the structures, respectively, in the corresponding resolution shell, half above and half below the mode. (a) R factors reported in the PDB; set 4 of models. (b) R factors recalculated with phenix. model_vs_data; set 5 of models.
