Hi,
If you set up a contrast that measures the difference between conditions (task) then you can treat this as a paired t-test with a single group. For different averages you may need to set up different design matrices though and run separate analyses.
All the best,
Mark

If true, this is different from our model design. Both of our factors (session and task) are within-subject: we have one group of 18 subjects scanned on the same task at PRE, and again at POST.
