[Freesurfer] Problem with mri_glmfit

Dear FreeSurfer experts,

I have a problem with mri_glmfit.

I am using the following script:

mri_glmfit \ --y lh.AspergerStudy.thickness.10.mgh \ --fsgd FSGD/AspergerStudy.fsgd dods \ --C Contrasts/AS-HC.mtx \ --C Contrasts/HC-AS.mtx \ --surf fsaverage lh \ --cortex \ --glmdir lh.thickness.AspergerStudy.10.glmdir

But when I run it, I obtain an error:

acad1215inv:01_freesurfer_processing acad1215inv$ mri_glmfit \

--y lh.AspergerStudy.thickness.10.mgh \ --fsgd FSGD/AspergerStudy.fsgd dods \ --C Contrasts/AS-HC.mtx \

gdfRead(): reading FSGD/AspergerStudy.fsgd INFO: gd2mtx_method is dods ERROR: must specify GLM output dir acad1215inv:01_freesurfer_processing acad1215inv$ --C Contrasts/HC-AS.mtx \

--surface fsaverage lh \ --cortex \ --glmdir lh.thickness.AspergerStudy.10.glmdir

-bash: --C: command not found

What could I do for solving this problem?

Thanks a lot

Naiara
