Hi, This
However, if I treat the P32 data as a twin (with twin law h,-h-k,-l ), the R/Rfree can down to 0.12/0.18.
and this
Even though no twinning is suspected, it might be worthwhile carrying out a refinement using a dedicated twin target anyway, as twinned structures with low twin fractions are difficult to distinguish from non-twinned structures.
suggest that your data is twinned. The lower R values are convincing. Do an R vs R analysis by loading up a model as well in xtriage to get a clue about the extend of the pseudo symmetry. Cheers, P
