Announcement: EDMAPS.rcsb.org Shutdown

05/09 

In fall of 2024, electron density map coefficients will be available in the public PDB archive for all X-ray structures. These map coefficients will be the same as used in wwPDB Validation Reports.

The new map coefficients files will replace the electron density maps and combined map coefficient files distributed by RCSB PDB and used by the NGLviewer at RCSB.org. These data (currently served by EDMAPS.rcsb.org) are calculated using publicly-available coordinate files and structure factor files and offered in DSN6 formatted map files and MTZ formatted map coefficient files. RCSB PDB plans to shutdown the NGL viewer by July 2024 (announcement) and will no longer need the data served by EDMAPS.rcsb.org.

RCSB PDB will be phasing out EDMAPS.rcsb.org:

  • June 28, 2024: DSN6-formatted map files will no longer be provided. EDMAPS.rcsb.org will only serve MTZ files with map coefficients.
  • Fall 2024: Electron density map coefficients will be available in the public PDB archive for all X-ray structures. At this point, EDMAPS.rcsb.org will be shut down, including access to MTZ files with map coefficients from this service.

To help users with this transition, RCSB PDB be holding a Virtual Office Hour on Thursday June 13, 2024 from 1:00pm-2:00pm Eastern, 10:00am-11am Pacific. Please register online for this event at https://go.rutgers.edu/psx4pr63.

Questions about this transition can be sent to info@rcsb.org.
