Dear FSL Experts,
I have a 2 x 3 mixed design. I have 2 sessions, so TIME will be a repeated measure. I have 3 groups, so GROUP will be a between subjects measure. I will use the model described in this post https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=FSL;a3eedcc7.1501 (also attached).
I'm struggling a bit with the contrasts. Please can you advise if I have got this right and help with the blanks?
Effect of TIME
[1 0 0]
[0 1 0]
[0 0 1]
F-test combining these 3.
Effect of GROUP
????
Interaction 1.
A > B
[1 -1 0]
Interaction 2.
A > C
[1 0 -1]
Interaction 3.
B > A
[-1 1 0]
Interaction 4.
B > C
[0 1 -1]
Interaction 5.
C > A
[-1 0 1]
Interaction 6.
C > B
[0 -1 1]
I have also read that I need to use --permute blocks for some contrasts. Can you advise which?
Kind regards,
Graham.
