Hi Alejandro,
I use this script only for the first round of refinement. The script generates PREFIX_001.eff early in the refinement, and then writes PREFIX_002.def file at the end of refinement. For subsequent rounds, I edit the .def file. Often, I control-C to stop to phenix.refine after PREFIX_001.eff is created, delete PREFIX_001.log to avoid overwrite error in next step, move PREFIX_001.eff to “start.eff”, edit start.eff to modify options not included in the script, and then run phenix.refine start.eff.
Best Regards,
Jack

Dear Jack
Thank you very much for your message!!
I see that the way you worked around the problem, was to have a detailed, “fully argumented” command, for each and every cycle, actually avoiding the use of the .def file that a n-th round of refinement generates (file that is supposedly useful as initial script for the n+1-th round, just by updating the desired input pdb model).
In any case, it does the trick (in my case having to add several more arguments that I personally need)
(still don’t quite get what the default phil and model are intended for, nor the phil_files: I see you just indicate “None” for all those, which I will do)
Thanks again
Alejandro

Hi Alejandro,
I had the same issues with command line batch refinement. The script below works with the new syntax. Replace PREFIX, SERIAL, MTZFILE, and MODEL.PDB with your file names. Of course, change the SG, restraint files, and tls definitions to match your system. You may also want to change the refinement strategy, as the one below is not the default. For the default files in the .eff or .def files, use None as follows:
default_model = None
phil_files = None
default_phil = None

Dear phenix users/developers
Some time ago there were several modifications on the names/specifications of important parameters/options (such as miller_array for structure factor files, etc)
Running phenix.refine by command lines (no gui) is my favorite, and I am now running into several difficulties:
1- what’s the difference between miller_array and default_miller_array; or model and default_model?
2- what’s the precise definition of phil_files and default_phil? What to change if I manually edit my .eff?
3- how should I use the new automatically created .def file for subsequent refinement cycles after I’ve manually rebuilt (I need to point to the new pdb input file: I usually screw this up, can’t seem to use the newly created .def as my starting instructions file anymore, it complains that I have problems in the right definition of the input pdb, or too many models...)
4- I often fall into a loop where by default newly created .eff files include a dry_run=true option (e.g. when I deliberately tell phenix.refine to overwrite previous .eff files)
Thanks a lot for clarifying on these issues: and sorry, for I couldn’t find obvious answers to them in the documentation (probably my fault!!)
Also, I am using phenix v 1.21.1-5286 (on a Sonoma MacOS laptop)
With best wishes
Alejandro
