Hi all

I want to specify a design matrix manually.

In the usual pipeline for analysis in freesurfer, one specifies the groups, regressors in the fsgd and then when mri_glmfit is run, it creates the design matrix.

For eg if I have two classes with 3 subjects each, in my fsgd, mri_glmfit would create the following  design matrix

1 0

1 0

1 0

0 1

0 1

0 1

If I want to specify the above design matrix manually, how and where do I specify the groups, regressors ?

Thanks in advance
