Dear FSL experts,
I am running a rs-fMRI analysis on four treatment groups and would like to know if I am going about my model design in GLM the correct way please.
the four groups are:
CTRL
FRST
MONO
AUG
The comparisons I wish to make are:
MONO vs AUG
FRST vs (MONO + AUG)
CTRL vs (FRST + MONO + AUG)
I have set up my contrasts as follows (as this is how I would do it if in a statistical program), but not sure if this will work in FSL
CTRL FRST MONO AUG
0 0 -1 1
0 0 1 -1
0 2 -1 -1
0 -2 1 1
3 -1 -1 -1
-3 1 1 1
Please tell me whether this makes sense or whether I have gone about it completely wrong.
Many thanks in advance.
Kindest regards,
Carolyn McNabb
