Re: [Freesurfer] Surface area of a define volume projection on cortical surface

It will not be one surface area for all voxels, each voxel will have it's own surface area. If you have a particular voxel in mind, then you can create a volume where that voxel is 1.0 and the rest 0, then map it to the surface and to fsaverage and see how big it gets.

Dear Freesurfer's experts,

Given the well known size of a voxel I would like to know the equivalent surface area once projected on the white fsaverage cortical surface.

Could anyone give me a proper way of computing this ?

Best regards, Matthieu
