PSVS systematically evaluates the quality of protein structures. PSVS integrates analyses from several widely-used structure quality evaluation tools, including RPF , PROCHECK, MolProbity , Verify3D Prosa II , the PDB validation software, and various structure-validation tools.PSVS provides standard constraint analyses, statistics on the PDB validation goodness-of-fit between structures and experimental data, and knowledge-based structure quality scores in standardized format suitable for database integration. Global quality measures are reported as Z scores, based on calibration with a set of high-resolution X-ray crystal structures.
