We ran a few subjects through recon1, 2, and 3 in an effort to get the volume of the hippocampus bilaterally. We emailed the list to find out if we should use aseg.stats or wmparc.stats. Doug wrote back saying that the hippocampus volumes should be the same. We went back & ran more subjects and they all appear to have a discrepancy between the number of voxels in aseg.stats and wmparc.stats for the hippocampus.  Some of the stats are the same-- just the NVoxels and Volume_mm3 differ between the two stat files.  we've attached a set of these aseg.stats vs wmparc.stats files.  Does anyone have any idea why we might be getting this bug and how we could fix it? 

 

Thanks!
