A thought - are these molecules related by a non-crystallographic
translation involving 0.5 along any axes. In such a case it is easy to
get the space group wrong, and assign a "1 axis when it is really only a
pseudo 21. if that happends your refinement will stick..
I think that at that resolu

according to

these are higher than expected. With that said, R/Rfree should not be a
fetish, and your model may be fine (i.e. a

Hello again!
Following my previous question, there was something wrong with the staring
model for molecular replacement. Now that is sorted, I have 8 complexes in the
ASU. After a few rounds of refinement with NCS and isotropic Bfactors, both the
Rfactor and Rfree get stuck at 30% and 36%, resp
