[3dem] Deposition of Half-maps for Certain EM Entries to Become Mandatory

[Justin Flatt]

 From February 25, 2022, deposition of half-maps for single-particle, 
single-particle-based helical, and sub-tomogram averaging 
reconstructions to the EM Data Bank (EMDB) will become mandatory. This 
change is in response to a long-standing community request to the wwPDB 
EMDB Core Archive and was also a recommendation from the 2020 wwPDB 
single-particle cryo-EM data-management workshop (white paper in 
preparation). Several recommendations from this workshop have already 
been implemented in the wwPDB OneDep system. These include improvements 
to wwPDB validation reports 
<http://www.wwpdb.org/news/news?year=2021#5ffc647df32c497fd6f7bf65> and 
enhancements for capturing metadata via the deposition interface.

Mandatory half-maps must be unfiltered, unmasked, unsharpened, and 
positioned in the same coordinate-space and orientation as the primary 
map such that they superimpose. The availability of half-maps will 
contribute to improved validation of EM structures as reflected in the 
wwPDB validation reports.

wwPDB strongly urges developers of cryo-EM processing software for the 
affected modalities to implement support for output of such half-maps 
(if this is not already available).

Any queries about this policy change can be directed to info at wwpdb.org.
