I am working on a surface based analysis using FS 7.1.1 and I would like to run mri_glmfit between two groups using the flag "--label" to restrict analysis within lobes.

I ran these commands on fsaverage

mri_annotation2label --subject fsaverage --hemi lh --lobesStrict lobes
mri_annotation2label --subject fsaverage --hemi rh --lobesStrict lobes

This created annotation files within the "labels"  folder of fsaverage, then I ran mri_glmfit using the flag --label lh.lobes from fsaverage 

I got this error message

mri_glmfit: could not scan # of lines from label file

I am ot sure what I am doing wrong. Thanks for guidance
