Re: [Freesurfer] cortical thickness in frontal lobe

you should weight by the number of vertices in each roi

Dear Freesurfer experts, We are new to Freesurfer. We appreciate your help & apologize if the question is simple. We need cortical thickness in lobes instead of parcellates. Is it correct to take the average of the parcelates from the aparc+aseg.stats file under subjid/stats folder. For example, cortical thickness of frontal lobe = sum of frontal parcellates  divided by number of parcallates . Do we need to do any correction such as weighing the surface area measurements ?

Thank you James
