Hi MRtrix3 experts,
I’m writing to ask about the streamline orientation. I want to track the fiber in cortical gray matter, ideally starting from the gray matter/ white matter interface to the pial surface. Now, I include only the cortex and generate a bunch of fibers. However, I cannot locate starting points and ending points (that saved in .tck file). That is to say, I don’t know if it’s close to the white matter or close to the CSF? Is there any tricks or function that I can use to achieve this?
For example, does the streamline always start from the seeding point? If that’s true, I can seed with GM/WM interface.
