Beta Version of PDB Validation Software Released

The PDB Validation Suite is a set of programs that create validation reports about 3-D structure data. It is designed to work with files in mmCIF or PDB format.

The beta version of this software can be downloaded in binary form for SGI, SUN, and Linux platforms from

This software is used in the Validation step of ADIT (AutoDep Input Tool) at and at the Validation Server at

Reports produced include an Atlas entry, a summary report, and a collection of structural diagnostics including bond distance and angle comparisons, torsion angle comparisons, base morphology comparisons (for nucleic acids), and molecular graphic images. In addition, reports from PROCHECK1, NUCheck2, and SFCHECK3 are also made available.
