Hi Joe,
to do this you can simply compose a script in whatever language you
prefer, which prototype looks like this:
for random_seed in random_seeds:
phenix.refine model.pdb data.mtz main.simulated_annealing=true
main.random_seed=random_seed output.prefix=str(random_seed)
where random_seeds is the array of random seeds, containing ~100 elements.
If you have multiple CPUs then you can obviously split it among them.
I'm not sure we have GUI for this and I guess this kind of task is best
run from the command line anyway.
Pavel.
