Yea, the real hard part is figuring out how to model the twins that are split
between groups. You might be able to create a bunch of groups. If you've
already created a design in FSL that you like, you can extract the design
matrix and use it in mri_glmfit with the --X option. Not sure about
Sorry for the delay ...
This looks like a fairly complicated design, and I'm not sure how to
think about it. What do you actually want to test in the end?
BTW, the FSGD file you have there will not work. The variables are for
continuous variables (eg, age) and not discrete variables (eg, sex

Dear FS List,
(apologies for reposting under different title)
I wanted to check if my GLM design for a surface based analysis is sound. I
am new to FS so please don’t skip over details.
I have 3 groups of monozygotic twins: low-risk, high-risk, ill.
