For WM, you can use aparc+aseg.mgz and use indices 2 and 41. Do you want
a particular GM or all GM?

Doug,

The file "segmentation.mgz" doesn't exist.

I think that you mean that segmentation.mgz stands

for either WM or GM. Can you provide me the

Hi,

I would like to extract the WM and GM segmentations

used for the final cortical thickness calculations as

nifti files. How can I do that?
