Dear Friends:
Thanks for answering my previous questions. I appreciate you spend time and
efforts to help someone you never meet before. Here is my one more question.
Assume I have two functional runs, e.g., f1 and f2. Both of them are block
design. f1 has 3 conditions, e.g., A, B, and rest, and 300 volumes. f2 has
two conditions, e.g., C and rest, and 200 volumes. Now, I want to compare
the BOLD signal changes of A and C, relative to the corresponding rests. How
to compare?
Can I put f1 and f2 in the same matrix? I tried this with spm2 before, but
the program complained the two sessions are different in volumes.
Best
Jiansong
