[phenixbb] Using Reference Structure in Phenix Refine

[John Pascal]

Hello Everyone,

I am refining against low resolution data, and I would like to use a
higher resolution model that is available as a reference structure.

There are multiple copies of the molecule in the asymmetric unit, each
with a different chain ID.  Does the reference PDB file need to
contain multiple copies, such that there is a match for each chain
(e.g. RESIDs and SEGIDs)?
Or does phenix figure out that the reference structure refers to
several copies of the molecule, and you only need a single copy in
the reference molecule PDB file?  Or will NCS restraints take care of
this?


Thanks.
-John
