Just remove that column. You don't need it or want it.

Ye,
If you use the DOSS model as Doug suggested, you have will not have a
column of 0s in the matrix. However, the group columns become the
covariate-adjusted thickness in each group (e.g. thickness at the mean
years of meditation across everyone) - which doesn't make sense as
non-meditators will
Dear Doug,
I am afraid that I don't see a difference between fsgd file and customized
design matrix in this case. If I were to set up my own design, the matrix
would still have a column of zero's -- unless there is a trick that I don't
know?
Thank you very much for your patience.
Sincerely,

There is not a way to do this using an FSGD and a DODS model. It will
work if you change it to DOSS (if that is appropriate). Otherwise, you
will need to create your own design matrix and feed it to mri_glmfit
with --X
