Thanks everyone, I agree, 18.4% Rwork and Rfree is too good to be true for a 3.4 Å dataset. The data was processed using autoProc and the staranisano mtz was used for MR. The completeness is only 38%. It could be that the Rfree and Rwork reflection sets are small because of this? What is the best way to check the number of reflections used for Rwork and Rfree? Is this dataset usable at all?
