What are you trying to achieve?: I’m trying to randomize two columns in my conditions file, one sound and one image, so that they do not always occur in the same pairs. E.g. sound 1, 2, 3, 4 and image a, b, c, d not always occurring in the combinations 1-a, 2-b, 3-c, 4-d. What did you try to make…

Sorry for the confusion. My code was coping with translating numbers to strings without ending .0. You just need listA.append(grid) In the trial routine you do need thisA=listA.pop() and thisExp.addData(‘thisA’,thisA) to select and record the value being used.

I’ve just written a demo called Independent Randomisation that should help.
