Dear list members,
here is another question from Utrecht, Holland.
The paradigm I want to study involves:
rest (r)
task1
task2 (control task)
so the design is:
r-t1-r-t2-r-t1-r-t1-r-t2-r
The TR is 3 sec. Each epoch consists of 14 scans. The total task
has 126 scans.
I think I made a correct designmatrix, when I used only activation
(t1 and t2) vs. rest. This was based on the data from the SPM
internet-site.
I'm not sure what is meant by SOA.
Anyway, I hope someone can help me
