so just to make sure I understand the manuals , if i have 2 test scores for
each subject and i would like to find voxels correlating with each test and not
with age should my design be:
group EV1 EV2 EV3
test1 test2 age
where all scores are demeaned
and the contrasts
EV1 EV2 EV3
1 0 0
-1 0 0
0 1 0
0 -1 0
considering i want to find both positive and negative correlations.
thanks
reut
