If I recall correctly DATAMAN does Wilson scaling in which the scale and B-factor are adjusted so the average reflection intensity in resolution bins are the same. I suspect it may not be required if all the data have been put on an approximately absolute scale by e.g. truncate (although that doesn't adjust the B-factor).
If you do end up scaling your data in dataman, be sure to go back to the original data for refinement once you solve the structure, or your B-factors will not be right. eab Francis E Reyes wrote:
Hi all Walking through multi xtal averaging with RAVE. I finally got a good mask and optimized NCS for my xtal forms. However, in the CRAVE manual I see this - the reflections in the input MTZ files *MUST* have been put on the same temperature factor scale prior to cross-crystal averaging (see the DATAMAN manual on how to do this) !!! Scale the separate datasets together? Wouldn't this just be a mess since the crystal should be non isomorphous to each other? Or does this say that within each dataset, all the data should be on the same scale (which would be if I used scala to scale) ? Am I interpreting this correctly? Thanks!
