[Freesurfer] question about volume of the hippocampus

Dear freesurfer developers.

I am working at department of neurology in university Hospital, Japan. I am beginner of freesurfer, please forgive me to ask you a basic question.

I want to measure the volume of the hippocampus in my patients. I was able to segment the MRI successfully and display the image in freeviewer. However, I could not recognize the way to obtain the volume of the hippocampus.

*I saw the "mail acheive" (http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg14679.html), however, I could not understand the way to look at the the aseg.stats.

Could you teach me the way for obtaining the volume of the hippocampus? I and very looking forward to hearing from you.

Yours sincerely, Junji Komatsu
