I have 2 different groups (healthy control and patients), I wanna do a voxelwise analysis using SPM, they are CBF maps.
I choose the 2sample t-test with following contrast:
first column -> HC // second column -> P
contrast -> [1 0] (for me the meaning is: positive relationship which HC CBF are greater than patients)
That's correct interpretation?
And this other's possibilities? [0 1], [-1 0], [0 -1], [1 -1]???
Thank you very much!!!
