Hello,
We've just started using phenix.refine and I'm a bit confused about
whether anisotropic ADP's are actually being used or not. On the wiki
(http://www.phenix-online.org/phenix_wiki/phenix.refine) it says:
<<
phenix.refine is the macromolecular refinement engine of the Phenix
suite. It features
* Individual as well as grouped B factor refinement
* Anisotropic or isotropic+anisotropic B factor refinement
* TLS refinement
>>
However, the documentation says
(http://www.phenix-online.org/download/documentation/phenix/phenix/structure_refinement.html):
<<
Current limitations
* No restrained individual anisotropic ADP refinement
>>
In my .def file I can set:
adp {
individual {
isotropic = None
anisotropic = chain a
force_all_to_be_refined_isotropically = True
}
and get ANISO lines in my output pdb. But I'm confused as to whether
this is actually refining with individual anisotropic b's for chain a
(analagous to refining with anisotropic temperature factors in
refmac). Should I be resetting the force_all... to false?
Can someone with more knowledge clarify this?
Thanks, the program seems to be working great otherwise!
