Hi James, yes you can turn it off: adp.iso.automatic_randomization_if_all_equal=false I will fix it for the case of zero macro-cycles. The fix will be available in the next PHENIX and CCI Apps. Pavel. James Fraser wrote:

I'm trying to do an Fcalc with "main.number_of_macro_cycles=0 main.bulk_solvent_and_scale=false export_final_f_model=mtz ", but the b-factors get randomized before the 0th cycle of refinement (see excerpt from log below).

Is there anyway to turn this off?

Thanks,
