# Loop Design

The first loop corresponds to a list of 11 conditions and this loop will be show 3 times (3 cycles). The first cycle, the system will show me a set randomly chosen. For the second cycle, I need the software to show randomly any of the remaining 10 conditions (all but the one that was randomly chosen previously). For the third cycle, I need the software to show me randomly any of the remaining 9 conditions (all but the two that were previously chosen)

Is that possible?

Hello,

I would say you can do it by playing with datamatrix, random and lists. For datamatrix see there:

Just for you to see an example I join an example doing what you want to do, but not on the conditions (if I understood) but on 11stims.

I hope it will help!

Best,

Thanks! I will check that out
