I really need more information to comment properly.
However just check that you are using the same reflections for both Rfree
calculations.
An Rfree of 26% seems low to me from a Se met phased structure at 2.1A -
there are usually small corrections to be made, What is the Rwork?
Maybe attach the
Dear all
I have got my se-phase structure with ccp4-CRANK2-SAD, and its Rfree is 0.26
when CRANK2 output, but the Rfree is higher to 0.36 when I refine it with
refmac or phenix-refinement. does it mean I got a wrong phase, or I didn't got
the right parameters when refinement.BTW, the
