Hi, 
I have a question about my inquisit code. 

I set a trial to be something like below. 

<trial POSO_posBG_shrt_ITI_1pt6>
/ validresponse = ("1", "4")
/ correctresponse = ("4")
/ stimulustimes = [0 = fixation; 800=noreplace (POSO);
1000 = blanks;
1100 = poso_goodtarget]
/ trialdata = [POSO poso_goodtarget]
/ beginresponsetime = 1100
/ timeout = 3200
/ responseinterrupt=frames
/ posttrialpause = 1600+(500-trial.POSO_posBG_shrt_ITI_1pt6.latency)
</trial>

I wrote the trial in this way with the following goals in mind: 
(1) Participants can make a response between the time window of 1100 to 3200ms from a trial onset. Their response latency in the trial could range between 0 to 2100ms. 
(2) Once they make a response within this window, the poso_goodtarget word will disappear (blank screen starts). 
(3) No matter how fast participants make a response or whether they make a response or not, the overall duration of a trial plus the immediately following posttrial pause will always be a set value of 3200 + 1600 = 4800. 
- If the participant make a response within 500ms (1600ms post trial onset), they will see the blank screen for a longer time (1600 + 500 - latency). 
- If the participant make a response between 500 to 2100ms, they will see the blank screen for a longer time. 

However, when looking at the saved data file, it doesn't seem like the post-trial pause duration is taking the trial response latency into account. 

I attached a simplified version of the experiment and the saved monkey data file. Could you help me understand why the script is not working in the way I intend it to be? Thank you!
