[buster-discuss] High R/Rfree at 1.6A

I am currently refining a structure at 1.6 A resolution using BUSTER
2.9.2 and extensive alternating TLS-refinement.
While backbone and geometry is o.k., my R/Rfree is stuck at 19.3/20.3
%. I don't have much experience at this resolution, but at lower
resolution I know that Buster usually gets much better R/Rfree than
other programs. This is why I am pretty sure that I am missing some
important option at this resolution. I have maybe 12 residues out of
250 that are disordered, but that cannot account for such high R
I tried to add hydrogens, but that actually increased the Rfree by 2%.
Does anybody have any suggestion or advice ?
Thanks a lot in advance
