Hello everyone, I'm working to automate making movies from 10,000 frame trajectories. Currently, my cxc contains the following commands windowsize 1920 1080 set bgColor white view zalign ligand inFrontOf #1 sel protein surface; surface color salmon; transparency protein 60 target s sel :UNL color sel dark slate gray; color sel byhetero sel :SIA color sel dim gray; color sel byhetero sel :UNL hbonds :UNL reveal true surface zone #1 nearAtoms ligand distance 15 select zone ligand 15; select add ligand select ~sel ~cartoon sel delete sel ~sel view ligand movie record supersample 4 perframe "~label; label hbondatoms" ; coordset #1 1,10000,50; wait 200; ~perframe movie encode output hbond.mp4 bitrate 6000 framerate 4 The above takes ~ 30 mins, and it's something I would like to do for whole libraries I'm screening. I think the longest process is "hbonds :UNL reveal true" while second longest is movie record and perframe. Is there a way to speed this up? Is there a way to take advantage of multi-threading if it isn't already enabled? If multi-threading is already being used, what can I change to be more efficient? I deleted the parts that I didn't need "delete sel" since they're not involved in the binding site, and I thought it would help speed up surface calculations while recording.
