    Hi Jeremy,

    Assuming that I have the following sequence in my experiment:

    sequence("consent", "instructions", randomize("exp-trials"), randomize("catch-trials), "end")

    Both the exp-trials and catch-trials are templates calling from two different csv files, which have different lengths. Is there a way to combine these two trials within the sequence command so that items from these two trials will be randomly presented until both lists are exhausted?

    Thanks!
    Alex

    Hi Alex,

    Are you looking for rshuffle("exp-trials","catch-trials")? Or randomize(endsWith("-trials"))? See the Ibex documentation

    Oh I did try rshuffle and I must have made some mistakes. It’s working now. Thank you so much, Jeremy!
