Access Structure Quality Metrics
wwPDB Validation Reports provide an assessment of the quality of a structure and highlight specific concerns by considering the model coordinates, experimental data, and fit between the two.
RCSB PDB Structure Summary pages contain the “slider” graphic from these reports that provides a visual summary and also link to the full PDF report.
Users can also access the PDF and XML versions of the Validation Report from the "Display Files" menu.
The 3D NGL viewer maps report information onto the structure. Clashes can be displayed as pink disks, and the full structure can be shown using “Geometry Quality” and “Density Fit” coloring schemes. Detailed information about this feature is available.
wwPDB Validation Reports use widely-accepted standards and criteria, recommended by community experts serving in Validation Task Forces. Reports are provided to data depositors during OneDep validation, deposition and biocuration; shared with journal editors and referees as part of manuscript submission and review; and distributed by the wwPDB at the time of data release.
