Running batch script in purely random order

astovall — Wed, 24 Sep 2025 14:20:50 GMT

Hello,

I want to run a batch script of three different tests in a purely random order (not related to group assignment or session). Is this possible? The selectionmode attribute doesn't seem to do anything in a batch element.

Thank you.

Below is what I’ve tried (apologies, I should’ve included this with my original post), but it runs the tasks in sequential order every time./ file = “script1.iqx”/ file = “script2.iqx”/ file = “script3.iqx”/ selectionmode = random

Yes, that's correct and works perfectly fine here. If you're testing with Inquisit Lab, close the application between runs. It may be that the randomizer doesn't get a new seed value otherwise and threfore produces the same order.

Ah, I think that was my issue. Closing Inquisit Lab and rebooting the machine fixed it. Thank you!!

Yes, this is possible. Set /selectionMode = random in the <batch> element.
