Improve Your Coordinates, Keep Your ID (Phase II)
02/18
wwPDB is pleased to announce that authors (PIs) of released PDB structures can update the model coordinates while retaining the same PDB accession code, thereby preserving the link with the original publication. In this second and final phase of the project, versioning functionality has been extended from structures deposited using the OneDep system to all entries (previously).
For entries submitted via OneDep (2014-onwards), depositors should log into the corresponding session at deposit.wwpdb.org and submit the request via the OneDep communication panel. For entries submitted via legacy systems, requests should be emailed to [email protected] with the PDB code included in the subject and body of the email.
Once submitted, the revised model will be processed by wwPDB biocurators and the updated version released immediately upon depositor’s approval. Versioning of PDB entries will be limited to changes in the coordinate files, with no changes permitted to the deposited experimental data. To limit the impact on wwPDB biocuration resources, PDB versioning is currently restricted to one replacement per PDB entry per year, and three entries per Principal Investigator per year. This restriction will be reviewed in 2021.
The most recent version of the entry will be made available in the PDB archive FTP (ftp.wwpdb.org). All major versions of a PDB structure will be retained in the versioned FTP archive (ftp-versioned.wwpdb.org)--more information can be found at wwPDB.org. The structure of the versioned FTP archive allows for future extension of the PDB ID code format. PDB entry 1abc would therefore be found in the folder pdb_00001abc.
Changes made to entries during versioning are considered to be either major or minor. Updates to atomic coordinates, polymer sequence, or chemical description trigger a major version increment, while changes to any other categories are classified as minor. Changes introduced are recorded in the PDBx/mmCIF audit categories.
