Script to color zone a map according to the underlying model
Dear All,
As an exercise in scripting, I am trying to write a script to imitate the appearance a published figure (from Toropova et al 2017). I would like to display a semi-transparent map which has been color zoned to match the underlying model in surface view.
ChimeraX does everything in the script apart from the last two commands, in which I color zone the map, and then make it transparent. I don't get any errors in the log to give me a clue what to change. If I omit these last two commands from the script and then make them manually from the command line after the script is finished, it works. Is there something I can change that would allow me to include the final two commands in the script? Any pointers would be much appreciated.

Try adding the line:
wait
... before those two commands. That will tell ChimeraX to draw a frame and do all the associated processing before moving on.

Hi Caroline,
Tristan is right, although I think the command may need to be "wait 1" which means draw one frame. (The wait command without arguments waits until ongoing motions complete and I'm not sure if it draws a frame when there are no ongoing motions.) The reason you need to draw a frame is because the volume surface for your new threshold level is not calculated until a frame is drawn. In a script graphics are not normally drawn until the end unless the wait command is used.
We saw this problem before and I put in a fix where volume surfaces are recomputed when the level changes when running a script. So your script should work without any changes in the current ChimeraX daily build. That fix was made April 7, so I guess you are using a ChimeraX older than that. I'd suggest updating ChimeraX instead of adding "wait 1" to your script.

Hi Tom,
That is interesting, I see what you mean. I'll go ahead and update my installation. Thanks for the explaination!
Best wishes, Caroline
