Intermixing stimuli from two loops

pbe

Hello,

I would like to request a bit of advice for a slightly tricky design in OpenSesame.

Background

My stimuli comprise two kinds of sentences that contain different elements, and different numbers of elements. These sentences must be presented word by word. Furthermore, I need to attach triggers to some words in the first kind of sentences but not in the second kind. Last, these kinds of sentences must be intermixed within a block (or a `sequence`) of trials, because the first kind are targets and the second kind are fillers.

Purpose

I would be very grateful for any advice on how to present stimuli randomly from either of two `loop`s within a `sequence` in OpenSesame. Currently, when I try this arrangement, the resulting script ends up with `run loop1` followed by `run loop2`, but I can't find a way to ensure that the overarching sequence pulls randomly from either loop over successive trials.

I have searched for clues in the tutorials, in the forum, and elsewhere online, but to no avail. 

I would be equally grateful for suggestions of alternative approaches.

Thank you very much

I solved this by first distributing all the words in each sentence across different columns in the stimulus file, yielding 'word1', 'word2', etc. Next, in OpenSesame, I created a sketchpad for each word. Last, to prevent showing any words that were blank, I entered conditions such as [word7] != NA in the Run if field of the sequence.
