How to terminate a script using a pushbutton i GUI?

Hi all,

I have a GUI with a few buttons that makes some analysis for me. The duration of this analysis can be in range of few seconds to few minutes.

How can I terminate this analysis (manually finish the script behind this analysis) using one of those buttons (e.g. with the caption 'STOP')?

Is there a way how to do this in GUI (command, keyword or anything else)?

Thank you very much for your response.

I'm guessing that if the scripts are taking that long you have some loops in there. One way to stop the scripts is to have the stop button set appdata that signals to the scripts that they should stop running. The loops in the scripts should check to see if this signal is telling it to stop or not before each iteration.

sample:

stopbutton callback

setappdata(0,'stopreq',1)

end

functiontostop callback

if ~getappdata(0,'stopreq')

     code here

else

   setappdata(0,'stopreq',0)
   break

end

for this to work the functiontostop must be interruptable.

Thanks for the response. I tried this but it did not work. What did you mean the function "functiontostop" must be interruptable?
