Hi Andreas,

My guess is that you have main.simulated_annealing=True also active in your parameter file. You need to set this to False, and then the refinement should proceed.

Dear all,

I'm trying to get DEN refinement going from the command line.  The run aborts quickly with the following error in the log file:

Sorry: Cartesian simulated annealing should not be turned on for DEN refinement. Annealing settings are controlled in the den parameter scope.

The DEN scope in input.def looks like this:

  den {
    reference_file = den_ref_Jun.pdb
    gamma = 0.5
    kappa = 0.1
    weight = 30
    sigma = 0.44
    optimize = True
    opt_gamma_values = 0 0.2 0.4 0.6 0.8 1
    opt_weight_values = 3 10 30 100 300
    num_cycles = 12
    kappa_burn_in_cycles = 2
    bulk_solvent_and_scale = True
    refine_adp = True
    final_refinement_cycle = False
    verbose = False
    annealing_type = *torsion cartesian
    output_kinemage = False
    restraint_network {
      lower_distance_cutoff = 3
      upper_distance_cutoff = 15
      sequence_separation_low = 0
      sequence_separation_limit = 10
      exclude_hydrogens = True
      ndistance_ratio = 1
      export_den_pairs = False
      den_network_file = None
    }

Annealing type is torsion from what I can tell.  What am I doing wrong?

Thanks.
