Hello FSL experts,
I am trying to compare the neural correlates of mood improvements between four respective groups.
At the first level, I ran an analysis comparing rest vs manipulation per SUBJECT.
At the second level, I ran the GROUP average of rest vs each group's respective manipulation.
At the third level, I entered each groups percent change in mood as a covariate of interest (lets say EV3).
Now, I want to compare the brain regions corresponding to each respective group's change (the covariate; EV3) in mood BETWEEN groups.
That is, I want to see if Group A employs distinct mechanisms at improving mood when compared to the mechanisms associated with improving mood in Group B and so on.
I have tried simply entering each groups respective cope corresponding to the contrast associated with mood change (EV3) in the data input category of the feat gui. Ive done this with lower level copes and the feat directories. The analysis simply crashes.
Any input would go a super long way. Thank you ahead of time. Please let me know if there is anything I can clarify.
