Use the Uppsala program DATAMAN for this, with the "RFree SHell" command.

A number of people have suggested to use different approaches to get rid of this reciprocal space binding effect. One of these people (Bart Hazes I think, correct me if I'm wrong) suggests to take reflections for the R-free as thin shells in reciprocal space. The thin shell is omitted completely from the target for refinement (I suppose omitting a shell of data completely will also have deleterious effects on the refinement, I don't know by how much). Problem is, none of the data processing programs or suites of programs has implemented this as far as I know. A
