Dear FreeSurfer Experts,
I am attempting to construct surfaces that are 1, 2, 3, and 4 mm interior from the GM/WM boundary (?h.white). So going gradually deeper into white matter from the GM/WM boundary. I have successfully used mris_fill to fill the ?h.white surface and mri_morphology to erode the resulting volume, but I'm not sure on the correct procedure to create the new surfaces. Any advice or suggestions on tools with options to use will be greatly appreciated!
My eventual goal is to project coregistered DTI data onto these more interior white matter surfaces.
Thanks! -Jason
