Hi Shani, it looks like your commands are right. How are you judging that the mask is thicker? What is the resolution of the DTI volume? When you binarize in a coarser space, you'll naturally not get it to line up with the surface, and the binary mask will naturally be thicker. doug On 02/21/

[Freesurfer] Generate mask from surface in diffusion space

2013-02-21 Thread Shani Ben Amitay
Dear freesurfers I'm using bbregister and mri_surf2surf to transform intermediate cortical surfaces and mid surfaces normals to diffusion space. Next I'm trying to generate volumes from these surfaces (in the same diffusion space), however the generated volumes are much thicker then the generated
