Hi Intekhab,
thanks for sending the files.
Your log file shows you are refining at 2.7A resolution and the
R-factors are 24/26% (which is not bad!), and the parameters you use are
main {
fix_rotamers = True
simulated_annealing_torsion = True
number_of_macro_cycles = 5
max_number_of_resolution_bins = 10
use_experimental_phases = False
}
.
Try this instead:
main {
number_of_macro_cycles = 5
ordered_solvent=true
}
ordered_solvent {
mode = *every_macro_cycle
}
Does phenix.model_vs_data confirms the need to use twin-target:
phenix.model_vs_data model.pdb data.mtz
?
Pavel.
