× Streamlining of EMDB’s Map Entry Release Process

Beginning April 15th 2020, the Electron Microscopy Data Bank (EMDB) will end its practice of releasing map entry metadata (so-called XML header files) prior to release of the primary map and associated files. For new EMDB map depositions, this metadata will not be available publicly in the EMDB FTP public archive until the map is released. For on-hold entries that already have metadata released there will be no change to the available data until the map is released. EMDB strongly encourages depositors to release their map entries as soon as possible. Abolishing the pre-release of EMDB header files is part of the process to harmonize the policies and procedures of EMDB and wwPDB. For more information about EMDB policies please refer to https://www.ebi.ac.uk/pdbe/emdb/policies.html.

The Electron Microscopy Data Bank (EMDB) is a public repository for electron microscopy density maps of macromolecular complexes and subcellular structures. It covers a variety of techniques, including single-particle analysis, electron tomography, and electron (2D) crystallography.

The EMDB was founded at EBI in 2002, under the leadership of Kim Henrick. Since 2007 it has been operated jointly by the PDBe, and the Research Collaboratory for Structural Bioinformatics (RCSB PDB) as a part of EMDataBank which is funded by a joint NIH grant to PDBe, the RCSB and the National Center for Macromolecular Imaging (NCMI).
