Dear all,
Starting July 21, 2027
* ThePDB Beta Archive <https://files-beta.wwpdb.org/>will replace the
currentPDB main archive <https://files.wwpdb.org/>. The current beta
archive URL will point to the main archive (details
<https://www.wwpdb.org/news/news?year=2026#69ebcdca1103c56d3f444159>).
* PDB entries that have been issued 4-character PDB IDs, including IHM
structures, will be accessed in this archive using their extended
PDB ID that prepends “pdb_0000” to the 4-character ID (e.g., 1ABC
becomes pdb_00001abc).
* OneDep will only issue 12-character IDs (prefix pdb_ followed by 8
alphanumeric characters, e.g., pdb_1000axyz).
- New 4-character PDB IDs will not be issued at this point.
-Entries with only 12-character IDs will follow a new DOI syntax.
<https://www.wwpdb.org/news/news?year=2026#69ebcf461103c56d3f44415a>
- Data deposited after July 20, 2027 will only be released in
PDBx/mmCIF and PDBML formats.
- Legacy PDB formatted files will not be generated for these entries.
ThePDB Beta Archive <https://www.wwpdb.org/ftp/pdb-beta-ftp-sites>is
designed to be scalable and extensible. All files in this archive are
re-organized using extended PDB IDs (including file naming and directories).
All PDB users, including software developers and journal editors, must
transition to this new archive directory structure, PDBx/mmCIF and
extended PDB ID format. Start using extended IDs and PDBx/mmCIF data
files today.
For any further information please contact us [email protected].
