The YASARA PDB_REDO interface

PDB_REDO is a databank of updated and optimized X-ray structure models developed by Dr. Robbie Joosten[1]. PDB_REDO re-refines the X-ray structures in the PDB using the original raw data (reflection files) with state-of-the-art technology to arrive at more accurate structure models (which typically have a lower R-factor and better structure quality indicators).

PDB_REDO is tightly integrated in YASARA. When you select to download a PDB file from the Internet (File > Load > PDB file from Internet), you can choose between the original PDB file from the RCSB, the re-refined file from PDB_REDO, or the better of the two. In the latter case, YASARA downloads both files, and picks the one with the better WHAT IF structure validation results[2]. You can also download PDB_REDO files from your Yanaconda macros or Python scripts using the LoadPDB command.
