Hello afni'ers,

In our experiment we have scanning sessions on 2 different days that are similar and I want to contrast conditions A-Day1 vs conditions A-Day2. So first I though of concatenating both timseries and contrast between A-Day1 vs A-Day2 conditions directly. However, I first have to contrast the A condition with rest on each day (A-Day1 vs Rest and A-Day2 vs Rest) before doing A-Day1 vs A-Day2...

-- in other words I need to code for : [A-Day1 vs rest-Day1] vs [A-Day2 vs rest-Day2]

I am not sure how to code that in 3dDeconvolve. I know how to code A vs Rest, but not the longer one.

PS. I can't do it at the group level cause we will only a few subjects....

Thanks in advance,

Pat
