Dear Doug and others,
I'm sorry to hijack this thread. I noticed in FSL list that it has been recommended to demean gender (and probably other categorical variables) in GLM. As far as I understand, this implies treating a categorical variable as a continuous one. However, I can also see that you recommend not treating gender (and other categorical variables) as a continuous variable in Freesurfer. I would much appreciate if someone can help me to address this problem. I'm CC'ing FSL list so others may also help.
All the best, -Arman

I thought that it would have. Are you coding age as a nuisance variable? Also, are you coding gender as a continuous variable? That is something you should not do.
