Hi Jorge,
the fsaverage subject has less surface area than any of the individuals.
We typically correct for this by including the average surface area in
the surfaces created by make_average_subject. For example:
mris_info ~/local_subjects/fsaverage/surf/lh.white
reading group avg surface ar
Ok, but my automatic procedure constructed the ROI
masks on the lh.sphere (not on lh.sphere.reg)of the
fsaverage subject.
Is it wrong to compute the area of a ROI in the
fsaverage spherical surface by adding the areas of the
triangular faces inside this region? (The area of each
triangular face be
Hi Jorge,
the ?h.sphere is the metrically optimal surface, but after spherical
registration, the ?h.sphere.reg has a fair amount of metric distortion,
which is necessary to align folds
cheers,
Bruce

Hello all
I have made changes in the thickness values in some
regions of a left hemisfere of a subject surface after
mapped it onto the fsaverage sphere.
The changes were made to have areas close to these in
the left colum of the following table:
My area Freesurfer number of vertices
