Dear CCP4,
Deposition of half-maps for single-particle, single-particle-based
helical, and sub-tomogram averaging reconstructions to the EM Data Bank
(EMDB), as announced previously in
https://www.wwpdb.org/news/news?year=2021#61afa92e5f450743ba4aa438, has
now 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
<https://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 i...@wwpdb.org.
Kind Regards,
David Armstrong
