Hi experts,

I am using 3dMVM to see how age effect fMRI as a quantitative variable. I got results Age F from the code. But F scores are all positive. I am wondering if it possible to get a β coeffector from 3dMVM? Or some effector could show the data is increasing or decreasing with age.

Thank you.

My code:
3dMVM -prefix Aud_glt3 \
-bsVars "Group*Age*Risk" \
-qVars "Age,Risk" \
-num_glt 3                         \
-gltLabel 1 Group -gltCode  1 'Group : 1*Singr -1*Contr'            \
-gltLabel 2 GroupRisk -gltCode  2 'Group : 1*Singr -1*Contr  Risk:'          \
-gltLabel 3 GroupAge -gltCode 3 'Group : 1*Singr -1*Contr  Age:'          \
