Ben,
I'd suggest that you use the "Specify All" option. If your not
comfortable with that option, then you could create the difference
images (A-B) for each subject and then use a two-sample t-test to test
for the interaction and effect of condition.
Best Regards, Donald McLaren

I'm trying to set up a repeated measures design with the factors (1) subject (2) group (patients/controls) (3) condition (2levels). However I can't add more than 58 subjects to the design.
