Hi Håkon,
could you give us more detail about what you are trying to achieve?

Dear FreeSurfers,
I am analyzing data from a few patients with quite severe unilateral temporal lobe damage (no or little brain tissue left both medially and laterally). The cortical parcellation in the damaged hemispheres seem - compared to the presumably unaffected contralateral hemisphere and other "normal" brains - all right in some parts, while other labels are misplaced due to the placing of temporal lobe labels which no longer exist. I was looking for some advice as to how to proceed:
Is it advicable to use the labels from the original (recon-all) cortical parcellation that seem well parcellated, and create ROIs manually by drawing in tksurfer/tkmedit the parts of the brain where the labels have been misplaced? Or should I create ROIs manually and don't use the automated cortical parcellation? Or is yet another approach more appropriate, for example changing the input used in the parcellation so that Freesurfer don't expect to find and label temporal lobe structures in the damaged hemisphere?
Thanks!
