This is best done by calculating the structure factors for the part you want to fix. (make sure the occupancies are set yo 0.8) The REFMAC hklout will contain F SIGF etc plus FCALC PHIcalc for that bit Define this file as your input hkl Then refine the 20% structure (occs=0.2) with input LABI FP=F SIGFP=SIGf FPARTi=FCALC_80% PHIPARTi-PHIC THis will refine the 20% part and add on the structure factors from the 80% without any refinement of that..
