The routine mtriage will evaluate the resolution in a map, compare half-maps, and compare model and map
Running mtriage is easy. From the command-line you can type:
phenix.mtriage emd_8750.map 5w0s.pdb
where emd_8750.map is a map (CCP4, mrc or other related format) and 5w0s.pdb is a model that matches the map
