[Freesurfer] question on GLM

2021-01-07 Thread Barletta, Valeria
Good evening Freesurfers! I am building a GLM with 4 classes (control_F, control_M, patient_F, patient_M) to check for differences in cortical thickness between patients and control accounting for the effect of gender and age on cortical thickness. How should my contrast be? Thanks a lot, Vale

Hi list, I'm performing cortical thickness among 3 groups by using GLM. I created a group descriptor file with 3 groups and 2 covariates (age and mean thickness). I performed 3 comparisons A-B, A-C, B-C. Now, for one of 3 groups (group C) I have: groups C=30 subjects; I'd like to divide it in some
