Problem with DRST code

I am having a problem with a Delayed recognition span test possibly related to stacking scenes. Particularly with a concurrent scene. Any assistance would be appreciated. I'll attach the code but I am clipping the main loop to annotate the parts that fail or fail after the 4 th loop. I have been reading code for 40 years but not much experience with Matlab. Thanks.

for i = 2 : numIters-1

if fixCells{i}.Success
if fixCells{i}.ChosenTarget == i

%goodmonkey(2000, 'juiceline',1, 'numreward',1, 'pausetime',0, 'eventmarker',50);
%Play correct Sound
con1 = Concurrent(tc_Correct);
con1.add(BoxCells{i});
scene = create_scene(con1);
>>>> run_scene(scene); >>>> No reward no Sound
idle(0); %test for sound
goodmonkey(2000, 'juiceline',1, 'numreward',1, 'pausetime',0, 'eventmarker',50);
idle(2000); %inter trial interval
scene2 = create_scene(tc_newScene);
>>>> run_scene(scene2); >>>> Runs correctly 3 times IE new box presentation has a sound
%idle(500);
scene3 = create_scene(fixCells{i+1});
run_scene(scene3);
else
trialerror(6); % wrong
>>>> scene = create_scene(tc_Incorrect); >>>> works correctly
run_scene(scene);
idle(700, [0 1 0]);
return;
end
else
trialerror(3); % Didn't touch any
scene = create_scene(tc_Incorrect);
run_scene(scene);
idle(700, [0 1 0]);
return;

The task is working as you programmed. AudioSound does not rewind the wav automatically. To play it again, you should create the object again or rewind the wav with the PlaybackPosition property before calling create_scene().

Another thing you should know about the scene framework is that stimuli are presented until the next scene (or idle) starts. Keep this in mind when you try to find out why one sound plays to the end and the others do not.

Resetting the audio file worked well. One file was very short and must have gone EOF. The other .wav file performed as you described. Odd to have an EOF stimuli not reset when recalled but resetting was the answer. Thank you more than you can imagine.
Thanks

There is always a case that you don't want to repeat the sound no matter how short it is. Maybe I can add an option for automatic rewinding.
