[phenixbb] Continue mr_rosetta after system crash?

[Terwilliger, Thomas C]

Hi Oliver,

You can restart from the end of the last completed step in mr_rosetta. Here is how:

At each stage, existing solutions are saved as a python "pkl" file and can be read back in to mr_rosetta with "mr_rosetta_solutions=xxx.pkl". These solutions can be displayed with "display_solutions=True". Existing solutions are stored as "mr_rosetta_solution" objects which keep track of the model and its history, the map_coefficients and labels, etc. These can be read in to mr_rosetta with the keyword "mr_rosetta_solutions=results.pkl" and used as inputs for subsequent runs, starting at any step that can use those solutions.

NOTE: You can re-start mr_rosetta only at the beginning of major stages (like "place_model", "rosetta_rebuild" etc)...but not in between.

Normally at the end of a major stage a .pkl file is written out with text like "type this to see all the results". You can almost always give your original command, the command "start_point=xxx" and "mr_rosetta_solutions=my_pickle_file.pkl" and it should then continue on from there.

(see also:   http://www.phenix-online.org/documentation/reference/mr_rosetta.html#viewing-solutions-and-restarting-with-saved-solutions)

Let me know if that doesn't do it!

All the best,
Tom T
