Hello Freesurfer Experts,

 

I am trying to compare the left and right hemisphere of a group of PD patients with Mass-Univarate LME.

 

From what I can see in the wiki tutorial, the mris_preproc only assembles data from one hemisphere at a time, which is not very usefull if I am doing a hemisphere comparison where each hemisphere is a different group.

 

I am thinking of getting around this issue by flipping each subject time point so that the right hemisphere is on the left and adding it as a new timepoint.

For example:

S01_1                    s01_base

S01_1f                  s01_base

S01_2                    s01_base

S01_2f                  s01_base

 

However, Can I still create the base file the same way using this?

 

also for the fsaverage, would make_average_subject still work?
