[phenixbb] phenix.refine & twinning

[Pavel Afonine]

  Hi Nick,

I looked through the files you sent and it looks like a bug in 
phenix.refine (someone reported the same problem before). Sorry about 
this. I fixed this bug yesterday so please use the latest PHENIX version 
from nightly builds available after January 17:

http://www.phenix-online.org/download/nightly_builds.cgi

Meanwhile a quick work-around is to remove a PDB file header (all REMARK 
3 records) from input PDB file.

Also, to make sure using twinning in refinement will make any difference 
(at least R-factor wise), run this command:

phenix.model_vs_data model.pdb data.mtz

and see it it tells the data is twinned.

Please let me know if you have any questions.

Pavel.
