I suspect most (if not all) refinement software now have a nice way to deal
with NCS in refinement locally. Technically, this means you can use NCS
restraints at any resolution and software should be able to be careful and
not wipe out local differences between NCS copies. In phenix.refine this is

I am not from any structure biology related group. So I have followed
literatures​ for the structure solution and analysis. At this level all
stereochemical and geometry looks good. The only parameter I could see with
some red bar was NCS difference.

Betreff: [ccp4bb] NCS difference
Hi all,
I am solving structure of one of the acyltransferse protein. We have collected
data at 2.16A resolution. Currently the Rfree is 0.2508 and Rwork is 0.2042.
My query is regarding NCS difference. Under validation tool of coot while
Minimizing a red bar may be tricky.. Have you tried to make it less red
(blue or may be green)? Otherwise Rw/Rf~20/25 is just fine at 2.2A
resolution. What exactly your worry is about?

Hi all,
I am solving structure of one of the acyltransferse protein. We have
collected data at 2.16A resolution. Currently the Rfree is 0.2508 and Rwork
is 0.2042.
*My query is regarding NCS difference.* Under validation tool of coot while
looking for NCS differene, i can find some residues with
