Electron cryomicroscopy (cryo-EM) has advanced quickly in recent years, which has led to an increased number of atomic structures. Several tools for the analysis and validation of cryo-EM data and models have been developed within the Phenix software package, such as the refinement program phenix.real_space_refine. To understand the quality of deposited cryo-EM structures and how they might be improved, we automatically re-refined models deposited in the Protein Data Bank that have map resolutions better than 5Å. The results are available on this web page.
