Hi Gang,
Thank you for your reply.
I still think the results are the same in sub-bricks GroupAge and GroupAge t, including the clusters location and voxel numbers. Now my code is like this:
-num_glt 4 \
-gltLabel 1 Age -gltCode 1 'Age :' \
-gltLabel 2 Group -gltCode 2 'Group : 1*Singr -1*Contr' \
-gltLabel 3 GroupRisk -gltCode 3 'Group : 1*Singr -1*Contr Risk : '\
-gltLabel 4 GroupAge -gltCode 4 'Group : 1*Singr -1*Contr Age : '\
>The t-test for age is for the slope or marginal effect: the amount of change in the response variable when age increases by 1.
If I am correct, the result of the Age t is smilar to the result of 3dRegAna -tcoef. Right?
Thank you.
