External Email - Use Caution        

Dear freesurfer experts,
we want to analyze the relationship between the cortical thickness and the neuropsychology  regressing out the effects of gender and age, but I don't know how to make the design matrix? Is it [0.5 -0.5 0.5 -0.5 0 0 0 0 1 -1 1 -1 ] ?

Best wishes,
Kan
