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

Dear freesurfer users, I have a question about the design matrix.We want to analyse the relationship between the cortical thickness and the neuropsychological test. We have two groups:TLE and extralTLE,one discrete variable:gender,and two continuous variable: neuropsychological test and age. we make the FSGD files like this: Title OSGM
Class MaleTLE
Class MaleextraTLE
Class FemaleTLE
Class FemaleexatrTLE
Variables Age Neuropsychology
Input subject1 MaleTLE 30 5
Input subject2 MaleextraTLE 40 6
Input subject3 FemaleTLE 50 8
Input subject4 FemaleLextraTLE 60 7
Is it right? And we want to analyze the relationship between thecortical thickness and the neuropsychology regressing out the effects of gender and age, how to make the design matrix? Look forward to your reply. Sincerely, Kan Deng
