hi, thanks for your quick reply.
 
I am a little puzzled, if volume of the line corresponding to Left hippocampus is the sum of the left and the right, why the volume corresponding to the right hippocampus is different from the left? How can I obtain the left and right volume of hippocampus respectively?
 
Could you explain how to measure subcortical volume in detail?
Do the volume corresponding to other subcortical structures have the same problem as the hippocampus?
 
Is there any detailed description on aseg.stats?
 
Thanks!

Hi, expert,
 
I would like to measure the volume of hippocampus, is there any way i can obtain the raw volume of hippocampus for each subject? How can I obtain it?
 
In fact, in the folder stats, there is a file named aseg.stat, where I can find a line which contains "ColHeaders  Index SegId NVoxels Volume_mm3 StructName normMean normStdDev normMin normMax normRange", I wonder whether the corresponding volume of the Left-hippocampus is what I want. I mean the volume of the left hippocampus.
 
 
Thanks a lot !
