Download Map Challenge Files

Maps submitted to the 2015/2016 Map Challenge are available here: ftp://public.emdatabank.org/maps2016. Two subdirectories hold submitted map data:

  • finalmap : final filtered maps and raw unfiltered maps
  • even_odd_maps : half-maps and (optional) mask used by the submitter to calculate FSC. 

Update June 2017: A third subdirectory holding uploaded particle parameter info is now also available: particle_params

Three additional subdirectories contain supplemental files based on the submitted maps.  These are provided to help assessors get started with analyses.

  • fitted-models : reference models fitted to each final filtered map
  • chimera : UCSF Chimera sessions and matrices with final maps aligned to common reference coordinates (README)
  • images :  automatically produced images with common views across each target (map-only and map+model)

All map, model, and session files are gzipped. Map files are named according to submission id (emcd###), targetname, and filetype: “emcd###_[targetname]_[filetype].mrc.gz”

  • [targetname]  = GroEL, Ferritin, Proteasome, TRPVI, BMV, Ribosome, or BetaGal
  • [filetype] = filtered, unfiltered, odd, even, mask

Download the full archive (29 Gb) using wget:

wget --mirror -r ftp://public.emdatabank.org/maps2016 

Download all files for a specific target:

wget -A "*[targetname]*" -r --mirror ftp://public.emdatabank.org/maps2016/

Rsync access is also available by email request to challenges@emdatabank.org (please include your public ssh key).

Files with reported voxel size for each submission, as well as other associated metadata, are available below. Note that a correction was made to metadata (resolution determination description) for emcd154_BetaGal on July 8, 2016.
