Hi All,
I have a structure at 2.45A which has been well refined. However, since the
R-merge at the last shell is above 1 (although I/sigmaI at the last shell
is more than 2), we now decide to cut back the resolution to about 2.6A. Is
there a way to do this based on the well-refined model instead
Please explain how you think that cutting back the resolution will improve your
model

Dear Yafang,
Is it the case that you collected these data on a Pilatus detector,
using relatively low exposure and high multiplicity? These types of datasets
always give what looks like alarmingly high values of R-merge, and many
people who are set in their ways (like so many reviewers still
this.

Hi Yafang,
perhaps you should calculate the actual resolution first (as described
here: *Acta Cryst.* (2013). D*69*, 1921-1934) and then go from that?
