(This is best answered on the marsbar list I think - Cc'ed)

Sorry - you want the conjunction between two contrasts in a single
structural ROI?  If so, then no, marsbar doesn't do that...    In
practice, if you want what most people mean by 'conjunction', you can
just see whether both your contrasts are significant or not - see the
conjunction paper series in neuroimage a few years ago...

Best,
