I've run a left-right asymmetry comparison in tbss between 2 groups of subjects. I set up the contrasts according to a previous thread on this topic. Here is my design.con for this asymmetry analysis on FA values:
/NumWaves 2
/NumContrasts 4
/PPheights 1 1
/Matrix
1 0
-1 0
0 1
0 -1
My understanding is that the first contrast compares L>R and second contrast compares R>L for group1 (and the same for the last 2 contrasts concerning group2). In the corrected p-value files, all the significant results are on the left hemisphere. I am assuming this is because the analysis was performed on left-minus-right skeletons. Is this correct?? Can anyone confirm?
