Hey Lorenzo,

I’m not an expert with that toolbox yet but I’ve enough knowledge to answer

Your categorical variable is basically your condition code for each epoch.
I assume you have an epoched dataset? If so, for each file you need to
generate a list with an integer per row corresponding to the order of
trials in your epoched file.

The continuous variable would be the same but it would not bin your data
into condition. So for example it would be the degree of brightness for
each picture (hence, continuous).

You may not need to have a continuous variable that depends on your design.

Does that help? Let me know if you want more help with how to generate the
