how to quit the psychtoolbox script without killing matlab

1
Hello
 
I use psychtoolbox on windows operating systems
I would be glad to find a way to kill psychtoolbox script in the middle of its running, without killing matlab using task manager
I know at Mac OS it is possible using apple dot controls

Hi Paleria,

 

This sometimes works, but not always (not sure why):

 

Open another window along with the command window (the editor window usually works)

If MATLAB crashes, press CTRL-C to navigate to the editor window (this should close the Psychtoolbox screen)

Minimize this window and you should be able to click into the command window

Type Screen(‘CloseAll’) to close the psychtoolbox screen

 

I’m definitely sure that this method will not work if the program is stuck in a “while KbCheck; end” loop.  The only way I’ve found to get out of that is to use task manager and close MATLAB.  I don’t know if there are any other cases where this method does not work.


Hope that helps,

Dan Little

Hi Paleria,

I poll for an "escape" keypress once on each trial, and if it's
detected I close all screens and break out of the loop. The polling
takes a minimum amount of time, and most times I have to do it anyway
to record subject responses. The code is below.
cheers
johannes

[keyIsDown, keysecs, keyCode] = KbCheck;
if keyCode(KBName('escape'))
SCREEN('CloseAll');
break;
end

Maybe this does not always work if intense code is looping or processing, but in simple situations of when the program hits an error, I seems to be able to just:
 
1.  Alt-Tab over to the MATLAB command window (and thereby hiding/minimizing the Psychtoolbox Screen.)
2.  Type "clear screen" at the command prompt.

Ah, my mistake.  I should have written ALT-Tab instead of CTRL+C.


Thanks for picking that up.

Hi Paleria,

what also works, even if your code has produced an
error, is hitting the Windows-key and after that
select the MATLAB command window again and typing
'screen closeall'.  In my experinece CTRL+C does stop
MATLAB, but it does not necessarily break you out of a
PTB screen. By hitting the windows-key MATLAB loses
focus, after which you can select the MATLAB window
you want to use again (that is, you can select the
command window again) and then close any PTB screen.
Still, there are instances where you will need to kill
MATLAB with the task manger wen you're stuck in a PTB
routine (e.g. when you've blocked your keyboard during
a stimulus presentation or something like that).
