Hi, All

Could any tell me how CCP4 handle free R flag? I know It is important to
select the same** FreeR reflections if I move to next step of refinement.
But everytime I start from fresh, the freeR Flag remains unchanged. The
Rwork and Rfree of my models are fine (20.7% and 22.9%). I thought Rfree
was randomly generated. I asked more experienced people in the lab and
neighbor labs, and didn't get a straight answer. Did I do something wrong?

Thanks and sorry to bother others.

Zheng (Joe)
