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?
