Updated Validation Reports for Released PDB Structures

Sept-2020: Updated validation reports for all X-ray, NMR, and 3DEM structures released in the PDB archive are now available. Of particular importance for cryo-EM, the updated report format includes EM map analysis, and fit of EM model to its map volume. FSC curves are also included to compare reported and estimated resolution, where either half maps or FSC data was uploaded.

2019 Model Metrics Challenge Outcomes Preprint

June 15 2020:"Outcomes of the 2019 EMDataResource model challenge: validation of cryo-EM models at near-atomic resolution" is available as a preprint at BioRxiv while under consideration for publication.
