You can use CCP4 programs SFALL and RSTATS to do this.
 You need to calculate the F and SigmaF from I and SigmaI from some
programs. In CCP4, you can use TRUNCATE to do this.
 Use SFALL to calculate Fcalc and Phicalc from your model structure.
 Use RSTATS to determine an R-factor between Fobs and Fcalc.
Note, you have to have your F's and SigmaF's in the MTZ format which is understable to CCP4 programs.
