TLS refinement results in an anisotropic b-factor component per atom. You then add to this the individual atomic isotropic b-factor and you’ll get something that’s still anisotropic — that’s what’s stored in the ANISOU records. 

Thanks,

Hi, everyone,
Can someone shed a light on B-factor refinement in PHENIX.refine.
I am refining the structure with 2.5 A resolution, with individual B-factors and automatically defined TLS groups. Despite isotropic refinement of B-factors I still see ANISOU entries for atoms.
I figured out that these ANISOU lines appear only after TLS refinement.
So the question is how these ANISOU values are calculated?
