​Hi Freesurfer experts,

I am looking at the effect of a genetic risk score (GRS) on cortical surface/thickness. I have two groups: patients, controls (male and female).

I want to include total brain volume and age as covariates. Is this possible using an fsgd file? Is there an example you could give? ​

Any advice would be great. Thanking you in advance Donna
