Hi Andre, here is the link to cctbx-based code that computes Uhkl according to your formula below, using model mean B and F000 that accounts for atomic model and bulk-solvent: https://www.dropbox.com/sh/g7sp7pqxst4ldj0/AAD1whlVD2mvAGoRa5jOF-fla?dl=0 I leave it up to you to read and understand

The CCP4 program you are looking for is "cad". Using the "SCALE" keyword you can apply an overall positive or negative B factor to any mtz data set. Negative B factors are sharpening, which is what you are trying to do. There is also another program called "ecalc", which is specifically

Dear all, We seek to calculate the distribution of Unitary Structure Factors, Uhkl, from a few datasets (at different maximum resolutions) for which the corresponding atomic models are already available at the PDB; this according to the formula (6.4), in the 2nd edition of Jan Drenth´s book:
