Hello Freesurfers,

I understand that the output of "mris_preproc" can be the input of "mris_glmfit". In mris_glmfit, a GLM is performed.

Does "mris_preproc" give you a smoothed average of all the subjects?

If that's the case, how can you perform a GLM with just the average? Don't you need the data (smoothed or not) of all subjects?

Thank you very much!

Sincerely,

Ye
