[Freesurfer] GroupAnaysis Tutorial question: GLM directory error

Dear Freesurfer,

My current subjects dir is: /Applications/freesurfer/subjects/buckner_data/tutorial_subjs/group_analysis_tutorial

When I run the following (from the tutorial):

mri_glmfit-sim --glmdir lh.gender_age.glmdir --sim mc-z 5 4 mc-z.negative --sim-sign neg --overwrite

I get the following error:

ERROR: cannot find /autofs/space/birn_045/users/BWH/buckner_data/tutorial_subjs/group_analysis_tutorial/glm

I tried the following:

mri_glmfit-sim --glmdir /Applications/freesurfer/subjects/buckner_data/tutorial_subjs/group_analysis_tutorial/glm/lh.gender_age.glmdir --sim mc-z 5 4 mc-z.negative --sim-sign neg --overwrite

With the same result.

Any suggestions?

Thanks!
