I'm relatively new to Freesurfer, and have mostly focused of the aseg.mgz segmentation. However, I am also interested in entorhinal cortex and loaded the label up in tkmedit. What I noticed was that it seemed each label essentially noted the border between white and gray matter, but didn't really cover all the gray matter...this seems to be true in all the labels I load in tkmedit.
In sum, I don't really know what labels are for, or how they differ from segmentations (is a segmentation a collection of labels?). How do I use the entorhinal label, and do the entorhinal-stats actually give the gray matter thickness despite appearing only as a border in tkmedit. I'm afraid I'm quite ignorant, and I can't seem to find a direct answer to them in the wiki.
Thanks, Joshua
