For those who may not have made it through all the CCP4bb postings in October-December 2011 on archiving raw images, I have posted a summary at the IUCR Diffraction Data Deposition Working Group forum page http://forums.iucr.org/viewforum.php?f=21 in which I have attempted to list the unique points made during the discussion, along with links to some of the original postings.
All the best, Tom T Tom Terwilliger terwilli...@lanl.gov
