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:
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.

Can phenix detwin
data? I have tried to input the twinning
law (l,-k,h) but phenix.refine does not
create the appropriate maps and there
is no appreciable change in R-factor. I
have attached my xtriage and refinement
logs.
