Dear FreeSurfer developers,
The surface area in fsaverage space that I extracted
with the first command below is not the same as the value under the same DK
brain region extracted from the lh.parc.stats file generated as a result of
preprocessing with the second command. I summed or averaged the surface area of
the vertices of the corresponding brain region under the fsaverage space, and
the result is still not the same as the one presented directly under the stats
file, and I would like to know why this is the case?
1. mri_surf2surf --srcsubject $subject --sval area.pial --src_type curv \
--trgsubject fsaverage --trgsurfval
$SUBJECTS_DIR/$subject/lh.area.pial.fsaverage.mgh --trg_type curv --hemi lh
2. aparcstats2table --subjects $subject --hemi lh --parc aparc --meas area
--tablefile lh.area.txt
Best,
Jinfeng Hou
