Hi guys,
I'm a beginner in Freesurfer and I want to perform an analysis of the
difference
between 3 groups in cortical thickness,volume and area having age, mean
thickness and etiv as covariate.
my design matrix for 3 groups
comparison as "1 -1 0 0
The value = (CU cortisol low - CU cortisol high) - (CI cortisol low - CI
cortisol high), so whatever that sign means. BTW, you are supposed to
decide the sign for a singed test *before* you look at your data.
