Postby Brian McMahon » Mon Jan 23, 2012 11:39 am

(Posted on behalf of Tom Terwilliger for technical reasons.)

This is a summary of some of the unique points made in a discussion on archiving images for PDB depositions Oct-Dec, 2012 on the CCP4 bulletin board. The IUCr has commissioned The Diffraction Data Deposition Working Group (DDDWG) to consider these issues. There is a public DDDWG web site where issues are discussed.
