Hello, I am trying to run coordinate refinement 5 cycles with first cycle of simulated annealing (torsion) via command line. Here is a part of my params file that I adapted from my colleges: refinement.main { number_of_macro_cycles = 5 target = *ml mlhl ml_sad ls simulated_annealing_torsion = True } simulated_annealing { mode = every_macro_cycle second_and_before_last once *first first_half } refinement.refine { strategy = *individual_sites individual_sites_real_space rigid_body \ individual_adp group_adp tls occupancies group_anomalous sites { individual = segid *A individual = segid *B } As a result I get the Error Unused parameter definitions: simulated_annealing.mode (file "refine.params", line 26) Could you help me with the syntax, please. Should I include sites definition for simulated annealing? Irina
