Hi Doug, Nick and other freesurfer users,
I have two groups and each group has a matched pair of subjects. I am keen on identifying cortical areas where the difference between the matched pair in group1 is greater than that in group2. How can I do this in freesurfer?
From the email archive it seems to me that -paired-diff option with mris_preproc should do the trick, however as I understand this will create difference maps such that subject1-matchedsubject2. For my purpose I would be needing the absolute difference between the pairs. How can I acheive this?
Thanks for any pointers, Mayuresh
