Dear Mark,
As it has been recommended on FIRST's documentation webpage, we tried FSL vertex analysis using both --useReconNative and --useReconMNI flags along with --useRigidAlign. However, --useReconNative yielded a lot of significant regions on both left thalamus and left pallidum while --useReconMNI yielded none.
Does this mean that our findings are in fact spurious?
Thanks,
Arash
