Hi
I'm tying to present stimulus in specific order, so every subjects could see stimulus in the exactly same order.
Following script is part of 'Go-nogo task' which I downloaded on inquisit webpage.
How can I select 'soa' in specific order I want? (not in sequence)

Note: Factorial design with
5 x SOA (100,200,300,400,500)
2 x Cue (1=vertical,2=horizontal)
2 x Target (Go, No-Go)
Vertical cue go / no-go ratio is 4:1 (80% go trials, 20% no-go trials)
Horizontal cue go / no-go ratio is 1:4 (20% go trials, 80% no-go trials)
Minimum number of trials required to fulfill the above conditions is 50.
Task runs 250 trials, i.e., each factor combination is repeated 5 times.

You enter values into the list element in the order you want and use /selectionmode = sequence.
<list somelist>
/ items = (10,20,20,10,30,20,30,30,10=
/ selectionmode = sequence
...
</list>
