Re: [Freesurfer] hippocampus volume are different after step.3

This is due to partial volume correction. Use the hippo volumes from aseg.stats.

Hi, there,

I ran a subject through FreeSurfer pipeline. I found that the size of left and right hippocampus in aseg.stats are larger than that of left and right hippocampus in wmparc.stats after step. 3.

If I want to compare the FreeSurfer segmented hippocampus with a manually traced hippocampus, which value I should use, the result from step.2 or step. 3?

Thanks a lot!
