External Email - Use Caution

Hello,

I also have the same error. I have been looking into all the tutorials available for Freesurfer v7 and trying to search why,

mri_glmfit-sim   --glmdir lh.age_gender_volume.glmdir   --grf 2 abs   --cwp  0.05 --2spaces

is not working and throwing an error showing the following in the screenshot:

Is it possible to clarify which tutorial to follow for grf or volume-based and surface-based group analysis in Freesurfer v7 and what all multiple comparisons corrections can be done for volume and surface analysis?

Any suggestion is appreciated.

Thank you.

Regards,

Jhelum Paul
