Hi Dale,
Can you try something else:
phenix.refine AutoBuild_run_12_/overall_best.pdb \ refinement.input.xray_data.file_name=\ AutoBuild_run_12/exptl_fobs_freeR_flags.mtz \ refinement.main.high_resolution=2.2 refinement.main.low_resolution=20 \ /usr/users/dale/geometry/chromophores/bcl_tnt.cif
This differs from your run only by substituting
AutoBuild_run_12/exptl_fobs_freeR_flags.mtz
for your 2 refinement data files. This is the exact file that is used in refinement by AutoBuild.
I tried this command, very similar to yours: phenix.refine AutoBuild_run_12_/overall_best.pdb \ refinement.input.xray_data.file_name=AutoBuild_run_12_/exptl_fobs_phases_freeR_flags.mtz \ refinement.main.high_resolution=2.2 refinement.main.low_resolution=20 \ /usr/users/dale/geometry/chromophores/bcl_tnt.cif output.prefix=junk2 The final output was: F-obs: AutoBuild_run_12_/exptl_fobs_phases_freeR_flags.mtz:FP,SIGFP If previously used R-free flags are available run this command again with the name of the file containing the original flags as an additional input. If the structure was never refined before, or if the original R-free flags are unrecoverable, run this command again with the additional definition: refinement.main.generate_r_free_flags=True If the structure was refined previously using different R-free flags, the values for R-free will become meaningful only after many cycles of refinement. Sorry: Please try again. The output from mtz.dump for your .mtz is Processing: AutoBuild_run_12_/exptl_fobs_phases_freeR_flags.mtz Title: Resolve mtz file.

I agree that you should be able to use your original data file instead. A possible reason why this has failed is that the original data file has a couple reflections for which there is no data...and which were tossed by AutoBuild before creating exptl_fobs_freeR_flags.mtz . Two files that differ only in reflections with no data will still give different checksums, I think.
All the best, Tom T
Hi Dale,
1) Why you specify reflection MTZ file twice in phenix.refine script?
I put the mtz in twice because if I put it in once phenix.refine complains that I have no free R flags. It seems to want one file with the amplitudes and another with the flags. Since I have both in the same file I put that file on the line twice and phenix.refine finds everything it needs.
phenix.refine looks for free-R flags in your main data file (1M50-2.mtz). Optionally you can provide a separate file containing free-R flags (I have to write about this in the manual). However, if your 1M50-2.mtz contains free-R flags then you don't need to give it twice. So clearly something is wrong at this step and we need to find out what is wrong before doing anything else. Could you send the result of the command "phenix.mtz.dump 1M50-2.mtz" to see what's inside of your data file? Or I can debug it myself if you send me the data and model.
If the MD5 hash of the test set depends on the resolution then certainly I could be in trouble.
No. It must always use the original files before any processing.
Does the resolution limit affect the MD5 hash of the test set?
No. If it does then it is a very bad bug. I will play with this myself later tonight.
3) Does this work:
(...) I'll try these but it will take a bit of time.
Don't run it until completion. Just make sure it passed through the processing step.
Pavel.
