Jan, tell your reviewer to join us all in the 21st century.

Diederichs and Karplus, Science, about 2 decades ago.  (Technically, 2012 <https://science.sciencemag.org/content/336/6084/1030?sid=8becd183-203a-4c7b-8c8d-815e18e15887>, but it really is a long long time ago now.)

Dear Jan,

You statistics look quite solid.

R-factors are not good criteria to judge the resolution cut-off. The weighting
schemes in refinement programs have much improved since the late 1990s. A good
starting point to learn more is
Rupp's "Against Method: Table 1 -Cui Bono?", https://doi.org/10.1016/j.str.

Best regards,
Tim

Hi everyone,
I’m trying to publish two structures at 3.1Å resolution with the following
refinement statistics:

Resolution range (Å)                           49.2-3.1
             49.3-3.1 Rfactor (%)
24.0 (32.4)                              23.4 (32.0) Rfree (%)
                                 26.6 (29.2)
26.3 (31.6)

Data collection
Completeness                                      100 (100)
               100 (100)

Redundancy                                        6.9 (7.0)
                 6.2 (6.3)

Molecules in asymmetric unit              1
             1

Average I/σ                                         14.1 (1.7)
                  15.3 (2.0)

Rmerge (%)                                          14.9 (100)
                 12.7 (100)

Rmeas (%)                                            16.2 (100)
                  13.9 (100)

Rsym (%)                                               6.2 (68.6)
                     5.5 (57.1) Wilson B-factor
        65.6                                        62.7

I’ve been told that the Rfree factor in the last shell are too high. Does
anyone know how I can improve these Rfree factors other then cutting the
resolution, which already is rather low?
