My problem boils down to a difficulty with generating a random subset from a list. I am not sure if this is possible, so before I drive myself crazy I figured I would come here. My specific goal is to code a task that will select a random group of faces of a specified set size from a list and then place those faces each at one of 24 pre-defined locations. I cant even seem to generate a list of random numbers, let alone do what I want to do. I already have a version of this task coded in python but I wanted it in inquisit. Should I give up, or keep trying. Below is the code I am using to test/practice using the list element.

<values>
/ test = 0
</values>

<list testList>
/ items = (5,3,4)
/ selectionrate = always
/ selectionmode = random
/ itemprobabilities = uniform
/ replace = false
/ poolsize = 50
</list>


<summarydata>
/ columns = (values.test)
</summarydata>


<text TestText>
/ items = ("testText")
/ txbgcolor = (white)
/ size = (3%, 4.5%)
/ hposition = 50%
/ vposition = 50%
/ hjustify = center
/ vjustify = center
/ erase = false
/txcolor = (black)
</text>

<trial TestTrial>
/ stimulusframes = [1 = TestText]
/ trialduration = 70
</trial>

<block 1>
/onblockbegin=
[values.test = list.testList.poolitems.1]
/ trials = [1 = TestTrial]
</block>


As I understand the pool attribute, I should be generating a pool of 50 items that are randomly selected but when I ask inquisit what the first item in the pool is, it is always 5. This doesnt seem to be very random at all. If I cant generate a random order to (at the absolute very least) shuffle my list, I cannot do what I want to do. Any help will be much appreciated.

Thanks,
Mike
