Hi, there,

I have a question about wmparc.stats and aseg.stats,

In aseg.stats, I read,

# Measure BrainSegNotVent, BrainSegVolNotVent, Brain Segmentation Volume Without Ventricles, 1132816.000000, mm^3
# Measure BrainSeg, BrainSegNVox, Number of Brain Segmentation Voxels, 1156812, unitless
# Measure BrainSeg, BrainSegVol, Brain Segmentation Volume, 1156812.000000, mm^3

In wmparc.stats, I read
# Measure BrainSegNotVent, BrainSegVolNotVent, Brain Segmentation Volume Without Ventricles, 206821.000000, mm^3
# Measure BrainSeg, BrainSegNVox, Number of Brain Segmentation Voxels,  244540, unitless
# Measure BrainSeg, BrainSegVol, Brain Segmentation Volume, 244540.000000, mm^3

Why the BrainSegVolNotVent and BrainSegVol are so small in wmparc.stats?
Those values in wmparc.stats are the sum of what?
If I want to get the correct Brain Segmentation Volume Without Ventricles, which value I should use? the one from wmparc.stats or the one from aseg.stats?

Thanks!
Guang
