Hi Doug,

Thanks for the response. Here is my glmfit command:

mri_glmfit \
--y lh.22q_age.thickness.10.mgh \
--fsgd 22q_age.fsgd dods\
--C 22q_age_2.mtx \
--surf fsaverage lh \
--label lh.orbitofrontal.label
--cortex \
--glmdir lh.22q_age_OFC.glmdir

And here is the error message:

gdfReadHeader: reading 22q_age.fsgd
