[Freesurfer] general info about FS

Hi, I'm at the very beginning with FreeSurfer. I found it when I was looking for software for brain segmentation and volume evaluation. I'm reading the tutorial and I tried to run a couple of patients. Someone told me that Freesurfer has not to do with volume based morphometry, but I don't understand exactly why (is it based on a different techniques but it has the same aim?). By the way I have two questions: - can this software be applied to single patient cases if I have some reference for different structures (for example hyppicampus)? - has freesurfer some relation to a similar commercial software called Neuroquant ? (I saw it at RSNA a couple of years ago and it looked like very similar).

Thanks
