EM Data Bank joins the PDB archive

7-March-2012: The EM Data Bank (EMDB), the primary archive for experimentally-determined maps obtained using three-dimensional electron microscopy methods, has joined the PDB archive (ftp://ftp.wwpdb.org), as announced previously.

The merger makes 3DEM results available in a single archive, including over 1300 electron microscopy derived maps from EMDB and 400 coordinates for EM map-derived models in PDB. It is also an essential step in the wwPDB's development of a Common Deposition & Annotation Tool that will cover all experimental methods, including hybrid methods.

With the addition of EMDB data, the physical size of the complete wwPDB archive jumps to roughly 180 GB (from its previous 130 GB). Sites that mirror the full wwPDB archive will need to increase storage capacity accordingly.

Summary information regarding the merger and detailed specifications for data access are posted at wwpdb.org/em/.
