Hi Luke,
you could, but perhaps it would be easier if you explained what your bigger goal is?

Hi Allison,
Sorry if i was unclear, what i'm interested in is the WM. As you say the current WM surface provides good information in separating the WM from the Gm, I would also like to have a surface which separates the WM from the subcortical structures. Is this possible?
Could i for instance take the volume information in aseg.mgz generate surfaces of the subcortical structures then some how remove these areas from the overall WM surface.
Alternatively, if I had a WM volume mask, that didn't include the subcoritcal regions. ie by sorting through aseg.mgz. could I somehow generate a new surface the is the boundary of this mask?
Thanks for the help. Luke

Hi Luke, For subcortical structures, you would want to use the volume information provided by the aseg.mgz and not information from the surfaces (which are intended for cortical measures). Allison

Hello,
I'm new to freeSurfer and just starting to look around so I apologize if this question is a bit naive.
When I look at segmentation results, that include deep brain nuclei (thalamus etc) I see that they are all contained inside of the white matter surface. is there away to edit the surface so that these boundaries are represented?
I imagine that this would change the topology of the WM region thus it might be difficult, Is there away to generate surfaces form these regions on there own?
