Hi Andre

sorry, I don't remember how many regions there are. Should be easy enough to count in matlab.

For the tractography question you'll have to wait for Anastasia to respond

Hi Bruce,

Thanks, yes I see these files in the mri folder. I like to use the 
apart.a2009s+aseg.mgz file (how many regions are included in this file?) now 
for tractography (every region as a seed mask) using probtrackx (sorry). How 
can I create a text file with all these seed regions (including their path)?

Thanks again
Andre

Hi Andre

if you ran recon-all you will have created a volume file names aseg.mgz
that has the subcortical segmentation (and an aparc+aseg.mgz that has
both subcortical and cortical in it)

cheers

Dear experts,
I use recon-all for the parcellation of my MPRAGE. As far as I can see this
procedure does not address subcortical regions - right? How can I
additionally perform a parcellation of subcortical regions?

Many thanks for your help
Andre
