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. 

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.
