use aseg.stats for the subcortical volumes. There is a difference between aseg.stats and wmparc.stats for the subcortical volumes because of the partial volume correction.

Hi,
I tried to find out this from previous contributions but got lost. There's some confusion on which file(s) to use for segmented volumes. FreeSurfer generates the following image and text files:
- aseg.mgz
- aseg.stats
- aparc+aseg.mgz
- wmparc.mgz
- wmparc.stats
To my best knowledge aseg.stats contains the volumes from the structures in aseg.mgz, but corrected for partial volume effects.
The volumes listed in the aseg.stats and wmparc.stats are in most cases different. Which volumes are the correct ones and to which of the image files are these referring?
