I tried running mri_glmfit and this error is occurring -

WARNING: gdfReadV1: class B,,,,, is defined but not used.

MRISread(/Applications/freesurfer/BAP/group_analysis_data/qdec/fsaverage/surf

This is probably related to some error in my .mtx file.

Thank you,

Dear Freesurfer experts,

I am a little bit confused on how I should construct my .mtx file to be used in mri_glmfit. The following variables are what I have used in my fsgd file:

GroupDescriptorFile 1,,,,
Title Study,,,,
Class B,,,,
Class NB,,,,
Variables ,,,Gender,Age
Input, Sub_ID,NB,F,71

Input, Sub_ID, B, F, 80

Please let me know if you need more information on my work. Thank you!

All the best,

Alex Job
