Dear SPMers:
Suppose there's a very simple experiment: one subject/one session, TR = 1s,
total 100 volumns, 1 slice/volumn. The stimulation is like this:
____________
____________________| |_____________
1 50 80 100 (second, or volumn)
After I performed design matrix under spm2, I want to know in "Select
contrasts", how should I define a new contrast (what is the vector for T/F
contrast)? I am a beginner, really don't know much about it.
Also, I find under spm2, I cannot define a contrast, I don't know why.
Is there anyone kindly help me? Many thanks!
Best,
Ping
