The new wwPDB Validation Server at https://validate.wwpdb.org now generates preliminary validation reports for structures solved by NMR and 3D Electron Microscopy, in addition to X-ray crystallography.
wwPDB strongly encourages the use of the Validation Server at any time during the structure determination process, but particularly when preparing structures for deposition to the wwPDB. Validation Server reports provide identical information to the ones generated at deposition.
Structural models may be assessed independently or together with experimental data (crystallographic structure factors or NMR chemical shifts) for validation of model/data correspondence.
