I wrote a Matlab Code with Psychtoolbox functions. When I use "WaitSecs" function with any time duration above 5secs, my code crashes. I replaced the WaitSecs with Matlab built-in function "Pause" and the code works just fine but since Pause is not as accurate as WaitSecs
I prefer to go on with WaitSecs. I ran the code on different computers and with different versions of Matlab and the problem persists. So is it the code I wrote that causes the problem?
P.S if you see no problem at first try 20 - 30 trials (stimulus presentation) and clicking during intervals.
The WaitSecs just after while t
Hey Saman,
how does the code crash? Can you provide the error message?
Greetings, David
P.S.: There is a type-o in Line 3: should be ButtonPress not ButtomPress
Hey,
Actually, I get no syntax error but when the code crashes, Matlab respond no more and then either it's closed automatically or I have to end it by Task manager. And sometimes I get the message on the screen implying Matlab is not responding and I have to close it. the last error is attached.
Thanks for the Typo hint.
Hey Saman,
my guess is that your inner while loop never reaches any of the break conditions due to something with the event cue of PTB inside this inner loop. Have a look at FlushEvents('keydown') or use KbWait instead of KbCheck.
Greetings, David
P.S.: Generally it is better to incorporate the various breaks into the while-condition instead of using while true. Makes the code much more readable.
