Hi,

I try to change one thing in a script that I created and used for study, but it's doesn't works and I don't undestrand why. 

I want to add a trialduration (1000 ms) on my actual trail (Go), but when I add the line /trialduration = 1000 in my trial, Inquisit told my that I do a mistake.

There is my trial :

<trial Go>
/ ontrialbegin = [
     values.gotype = list.Go.nextvalue;
     values.trialcount+=1;

if (parameters.runRandomITI == true){
values.ITI = list.intertrialIntervals.nextvalue;
} else {
values.ITI = parameters.fixedITI;
};

   trial.Go.insertstimulustime(picture.X, (values.ITI));
  trial.Go.insertstimulustime(clearscreen, (values.ITI + parameters.pictureDuration));
]

/ stimulustimes = [0 = clearscreen]
/ beginresponsetime = values.ITI
/ response = timeout(parameters.RW)
/ validresponse = (57, noresponse)
/ correctresponse = (57)
/ response = timeout(parameters.RW)
/ trialduration = 1000

/ ontrialend = [
 list.accuracy.insertitem(trial.Go.correct, 1);
 list.accuracy_G.insertitem(trial.Go.correct, 1);
 
 if (trial.Go.correct)
{
list.latencies.insertitem(trial.Go.latency, 1);
list.latencies_G.insertitem(trial.Go.latency, 1);
};
values.itempic = picture.X;
trial.Go.resetstimulusframes();
]
/ recorddata = true

</trial>

My script works well without the "trialduration". I just need that the stimulus "Go" appear for 500 ms and 500ms before the next stimulus. I hope you could help me.

Thanks in advance,
Best
