Dear Freesurfers and experts
Does anyone know how to flip hemisphere surfaces (cortical
thickness) for with-in group analysis?
I am analysing a cohort of unilateral chronic knee OA
patients and want to within-group correlate the cortical
thickness changes with the mechanical pain threshold.
(A perfect study would be having only Rt. or Lt. knee pain
and then the hypothesis would be a contra-lateral brain
cortical thickness changes) but since I have a mixed patients
of Rt and Lt knee pain, I want to flip only one group to match
the other and make them all as they were having same
laterality, and then do a correlation analysis using QDEC!
Any help will be much appreciated
Thanks
Hamza
