I would find the sites from the PHIC - you need to use CAD to add Fcalc PHIC and FOM to the original data with Fnative Fderiv DANOderiv etc I usually then use SCALEIT to scale native and derivative to Fcalc - then you know you are roughly on an absolute scale
Then feed those sites into Phaser_EP and it will refine occupancy etc and give you phasing power Eleanor On 16 December 2013 09:21, Tim Gruene <t...@shelx.uni-ac.gwdg.de> wrote: > Hello David, > > I would use the SAD target function of refmac5 for the anomalous > occupancy.
