Hello all,

I'm new to surface analysis.

I have 2 groups (patient and healthy control) that i want to check differences between.
I want to perform cortical thickness/ surface analysis.
My categories are
  Patients, healthy control, age, TIV,  father age, mother age.
Where age & TIV are covariates of no interest. and father and mother age are covariates of interest.

I have already preprocessed the data (recon-all), but how can i proceed?
Any online guide on steps for surface analysis? also making a design such as the above?

Yas
