[Freesurfer] FSGD error: class Input not defined

Dear Freesurfer experts,

I am trying to perform the resting state fMRI analysis as in: http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkthr...

I got stuck with the STEP8, when I tried to use my own fsgd file. I tried to test for two group difference, no covariance as in: https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf2G0V

But I am getting this error: mri_glmfit --y fc.lpccseed.surf.lh/L_PCC/ces.nii.gz --wls fc.lpccseed.surf.lh/L_PCC/cesvar.nii.gz --fsgd ../glm_file.fsgd --C ../group.diff.mtx --surface fsaverage lh --glmdir my-glm.wls --nii.gz gdfRead(): reading ../glm_file.fsgd Input line 1, subjid = HM-HR10-002Rest Group1, class Input not defined FSGDF Format Error: file = ../glm_file.fsgd, tag=Input

I am testing the pipeline so just 8 subjects so far. I've checked the ces.nii.gz and cesvar.nii.gz and both of them have correct dimensions of 163842 x 1 x 1 x 8.

Thank you for your help in advance.
