PDBj now only provides the wwPDB calculated electron density maps through our EDMap service, where we previously used our own generated map data.

From 2020-09-23, all legacy ED Map entries have been replaced by the wwPDB-standardized ED maps calculated from the map coefficients, which were calculated using the Buster software (Global Phasing Ltd), as part of the wwPDB validation pipeline.

The updated map files are available from our FTP site ( along with the validation reports. In addition, users can also download them from our web interface via PDBj Mine and the PDBj EDmap service.
