hello everyone
I just noticed my model would give two very different Rfree
values from refmac depending which mode I use to refine it. Rigid
body it gives a Rfree value of 24.57% while restrained refinement
gives a value of 27.96%. Both are processed at 3.1angstrom
resolution. I am confused as to which number to believe. Should I
keep refining with RB refinement or go back to RR even though it give
me a higher Rfree value? Thanks.
