Hi Alexei, at this resolution you most likely need to refine isotropic group B (one B per residue or so) or/and do TLS refinement (on top of it). Cheers, Pavel. --- Pavel V. Afonine, Ph.D. Lawrence Berkeley National Lab, Berkeley CA, USA (http://www.lbl.gov/) CCI: Computational Crystallograph

[ccp4bb] TLS refinement at low resolution

2008-03-26 Thread Alexei Datsuk
Hi, I have a question with B-factor and TLS refinement. My protein diffracts only to modest/low resolutions (3.4 A). I've been refining isotropic B-factors for main chain and side chain (not individual atoms) because I'm worried at this resolution I don't have enough observations to justify indiv
