Hi Michael,
It looks like lateral venous sinuses are included in this subject and as Bruce says, since the intensity is very close to cerebellar cortex, they are difficult to distinguish. It depends on what you are after in your analysis if you need to take care or not.

Hi guys,
I was just wondering approximately how often the aseg volume will need manual edits. I know the tutorial says very rarely but I noticed that most of my subjects have non-brain matter (I think) incorrectly labelled as cerebellum.
Attached is a pic of what I mean.<aseg.png>
