Hi - sorry, no I meant to omit contrasts which were not possible, and amend your high-level design accordingly. You will probably need to chose "inputs are copes" option rather than "inputs are FEAT directories".

Cheers.

Hi Steve, thanks for your reply.
I think I didn't quite get your idea: do you mean to contrast "relatively
slow > relatively fast" for each subject, even if "relatively slow" would
mean "medium" for one subject and "actually really slow" for the next? This
I could do...but is there any way to get some sort of parametric design over
*all* levels of speed at the end, then?

Thanks again,
Cornelius
