Re: [Freesurfer] Merge both hemispheres in cortical parcellations

Hi Carme

what measure do you mean? If you wanted an average it would be:

average_thick = ((nvertices_lh) * (lh_average_thick) + (nvertices_rh) * (rh_average_thick)) ------------------------------------------ nvertices_lh + nvertices_rh

Dear FreeSurfer users,

I've been looking for an appropiate way to merge both hemispheres in the Desikan parcellations but I can't find it in the list.

Which formula do I need to use to consider, for example, the bilateral posterior cingulate as an only measure (not lh and rh separated)?

I'm not sure if I can just add them in a mean...

Thank you very much for your help!
