Re: [Freesurfer] significance in unknown region

Hi Greg,

we usually mask that region out (set it all to 0). Each subject should have an ?h.cortex.label file for this purpose, or you can do it in the fsaverage space.

cheers, Bruce

Hi All,

I have wondered what is done in the medial and inferior region where a patch needs to be put across to seal each of the two hemispheres. The variables , thickness etc... have some value in the region as we see a representation on the thickness maps. Is something like averaging with a diffusion equation i.e. computing a distance weighted average of the border of the surounding real cortex performed ?

thanks

curious Greg.
