It resamples them to a common space (the "average" subject) but does not average them together. The result is a "stack" which is a single file with multiple subject it in it ready for GLM analysis doug

Dear Doug,
Thank you, but I am only more confused after reading the summary. The summary basically reaffirms my understanding that "mris_preproc" gives "an average subject". How can this be an appropriate "data" for GLM, which for sure needs multiple data points?
Thank you!
Sincerely, Ye

Hi Ye, have you looked at the mris_preproc help? You can access it with mris_preproc --help. Let me know if that does not answer your questions doug On 4/6/14 6:09 PM, ye tian wrote: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!
