Hi Alejandro, sorry, it's not documented. In your case use "once" or "first_half", which means the SA will be performed in a middle of refinement ("once"; at N/2 macro-cycle, where N is the total number of macro-cycles) or during first N/2 macro-cycles.

Dear Phenix users,

I can't find information on the precise meaning of the different modes to perform SA during refinement; some choices are self-explanatory (such as "every_macro_cycle" or "second_and_before_last"), but what about "once" or "first_half"? (in my particular case, I want to perform only one simulated annealing routine on the second macro_cycle: can I use "once"? but, where should I define at which cycle to perform it?)

Thank you for your help,

Best,
