Hi Pavel, I'm using 1.6.1 r393. The logfile shows 10 "Mask optimization: start' entries in 1 macrocycle total composed of rigid_body (2 zones), individual positions and adp refinement. I'll try the latest built tomorrow and see if that makes a difference.

Which version are you using? Pavel. On 5/26/10 12:49 PM, Schubert, Carsten [PRDUS] wrote: Hi, Is there a way to turn off the mask optimization step in 393? I tried 'main.optimize_mask = False' but that does not work. The program spends a substantial amount of time in repeated mask optimizations and I am trying to shave off a couple minutes for each run...
