Dear all,
I use phenix.refine to refine a structure.
Firstly, I used --dryrun to generate an .eff file. The command is "phenix.refine --dry_run 7_44.mtz 7_44.pdb refinement.input.xray_data.r_free_flags.generate=True refinement.input.xray_data.r_free_flags.max_free=1000”
Then I use run the program by typing “phenix.refine 7_44_refine_001.eff” It runs correct!
After that I use coot to modulate some parts of the structure, then I want to refine the structure again. I type “ phenix.refine 7_44_refine_002.def”
This time I got the following error message:
Not a suitable array of R-free flags: refinement.input.xray_data.r_free_flags.label=R-free-flags
Sorry_Not_a_suitable_array: Not a suitable array of R-free flags: refinement.input.xray_data.r_free_flags.label=R-free-flags
To override the suitability test define: refinement.input.xray_data.r_free_flags.disable_suitability_test=True
I checked the generated file by phenix “7_44_refine_data.mtz” I does contain a column labeled as R-free-flags. I paste part if it below.

Then I regenerate a new mtz file with FreeRflag by XDSCONT, then I revise the .def file accordingly and rerun the program. I got same error message:Not a suitable array of R-free flags: refinement.input.xray_data.r_free_flags.label=FreeRflag
Sorry_Not_a_suitable_array: Not a suitable array of R-free flags: refinement.input.xray_data.r_free_flags.label=FreeRflag
To override the suitability test define: refinement.input.xray_data.r_free_flags.disable_suitability_test=True
I checked my new mtz file, it dose contain a column labeled as FreeRflag
Why there is an error message? How to solve it?
Thank you so much!!
Best wishes!
