Dear FSL-experts,
I got three groups each tested two times (pre- and post a specific training) and no want to compare the CHANGE from the 1st to the 2nd scan between the groups.
Is this possible with a Multi-Session & Multi Subject test?
e.g. First step - Fixed Effects:
to calculate the pre-post change for each subject
group
Input1 1 1 0 0 0 0 0 0 (for subject 1 in group 1 - post-training)
Input2 1 -1 0 0 0 0 0 0 (for subject 1 in group 1 - pre-training)
.....
Input10 2 0 0 0 0 ... 1 0 0 0 0 0 0
Input 11 2 0 0 0 0 ... -1 0 0 0 0 0 0
...
Input 20 3 0 0 0 0 0 0 ... 1 0 0 0 0 0 0
Input 21 3 0 0 0 0 0 0 ... -1 0 0 0 0 0 0
and the Contrasts:
C1 subject1 1 0 0 0 0 0 0
...
C10 subject10 0 0 0 ... 1 0 0 0 0 0 0
And for the group effect: ME analysis - with the lower level FEAT directories:
3 groups
group
Input1 1 1 0 0 0 0 0
...
Input10 2 0 0 0 0 ... 1
and so on... Would that be correct? or how do I manage to compare the pre-post CHANGE between the three groups?
Thank you very much for your help!!! Daniela
