Hi René
our volume calculation corrects for partial volume effects, so it does
more than just counting voxels.

Hello FreeSurfer Developers,
I was wondering about the volume calculation of the structures in the
aseg.stats file.
VoxelVolume_mm3 0.512
NVoxels 8616 Volume_mm3 4312.4 StructName Right-Hippocampus
After my calculation of NVoxels * VoxelVolume I get a slightly different value.
0.512*8616 = 4411.4
Where does the difference come from?
Thanks,
René
