Dear users,
What is the allowed range of difference
between R and Rfree for structures with twinning?
I have a data in R3, after MR (dimer in asu) and
Refinement using Refmac-5.5.0102, I ended up getting
R ~ 0.231 and Rfree ~ 0.293, difference seemed to be
little high.
For twinning correction, twin refinement option in
Refmac was used. Twinning fraction ~ 0.1. And during
refinement (10 cycles) the R-factor was not converging.
So is this behavior observed only in case of twinned
structures?
Kindly give some suggestions.
Thanking you
With Regards
kavya
