Rotating 4 stimuli lists to 4 conditions?

  Hi Helio,

  The easiest way (in my opinion) is to use python coding inside an inline_script to assign lists to conditions. Using loop tables directly requires somewhat convoluted adjustments. In an inline_script, you can do stuff like this:

  import random
  conditions = ['a','b','c','d']
  stim_list = [[1,2,3],[3,2,1],[1,3,2],[3,1,2]]
  random.shuffle(stim_list)
  matches = zip(conditions,stim_list)
  

  Is that clear and does it help?

  Hi Eduard, thank you for your response, unfortunately, I can't quite figure out how to implement this. Specifically, how do I assign the stimuli sequence produced by this script to the to the trial sequences in the block loops?

  thank you,
  Helio
