The aseg.stats is computed with a partial volume correction at the boundaries of the structures, tkmedit just counts voxels.

Hi FreeSurfer:
when I compare a brain structure volume count on the aseg.statsfiles with a volume of same structure measured using tkmedit "Segmentation Label Volume Count" feature to display on TkMedit Tools window. They are closer but not the same, usually about 3 to 10% difference. Why?
Thanks,
Yuan
