Hi Petra, you have mixed up a class with the level of a factor (an easy
thing to do). From your FSGD, it looks like you would need 8 classes,
each class would be a combination of a level from each factor. So one
class would be control-male-adni, etc. Once you have a proper FSGD file,
FreeSurfer
I want to run a GLM DODS in Freesurfer to test whether patients differ from
controls with regard to cortical thickness, meanwhile I want to control for
several variables, both discrete as continues.
This is my manually made fsgd file
