Dear FreeSurfer experts,
I am trying to create an average subject based on a matched subsample (2 different scanners, patients and healthy controls).
I successfully ran make_average_subject receiving a "newtemplate". Now I am unsure how to proceed:
As far as I understand it, according to the SurfaceRegAndTemplates page (http://surfer.nmr.mgh.harvard.edu//fswiki/SurfaceRegAndTemplates) I should use mris_register for each subject from my subsample receiving ?h.sphere.reg.newtemple files with which I should make again an average subject, let's call it "newnewtemplate".
Is that correct?
Now, if I want to assemble the data into common space using mris_preproc: what do I need to specify? Would --target be the newtemplate or newnewtemplate? Do I need to specifiy the --surf-reg as well?
On the other hand, I read in one of your tutorials that I only need to run make_average_subject receiving a "newtemplate" which I then specify using mris_preproc as --target and that --surf-reg is not needed.
So what would be the correct way to use my own template for the group analysis?
Many thanks for you help!
Best wishes Christina
