As we described in the Download page, PDBj produces the 20070731 snapshot which is the latest release before the remediation was applied. It is now available from the PDBj snapshot archive. So, we have decided to remove it and will change the directory structure in PDBj FTP as follows:
And we will reconstruct as the following after the version 3.15 PDB archive will be released:
We will keep ftp://pdb.protein.osaka-u.ac.jp/v3/ as a symbolic link to (updated) ftp://pdb.protein.osaka-u.ac.jp/ in the meantime. But we encourage you to update your services/software to the new directory structure AFTER the change.
We will announce the release date for version 3.15 PDB archive when it will be confirmed.
Sorry for your inconvenience and thank you for your kind understanding.
