Hello again,
and thank you, Steve, for your quick answer. I would still bother you with
an additional question. In FSL, is it possible to use "functional masks"? As you may remember, in my design, I had two types
of tasks, L and C, and each task had two situations, L1 and L2, and C1 and
C2. I would like to create a mask using comparisons L2 vs. L1 and C2 vs.
C1, and make a direct comparisons between the tasks (L2 vs. C2 and L1 vs.
C1) using only those voxels activated in this mask (instead of the whole
brain). According to your advice, I have to make one of the conditions in
my design a "rest" condition, so how to make a mask described above?
