Hello MRtrix Community,
I am currently utilizing
tckgen and seeking clarifications regarding the seeding process, particularly with the
- When using
-seed_image mask, I noticed that not all voxels in my mask are initiating fibers. Can you explain why this is the case? How does the
-seed_cutoffparameter influence whether a voxel in the mask becomes a seed point for fiber tracking? Even if i lowered it, there were still no fibers from some parts of the mask.
- I’m also interested in understanding the use of
-seed_grid_per_voxelin conjunction with the
-seed_imageoption. How does
-seed_grid_per_voxelfunction differently from
-seed_image, and under what circumstances would one be preferred over the other?
- Regarding the
-seed_cutoffoption, how does it affect the seeding process in terms of fiber tracking initiation ?
Your insights into these parameters and how they interact in the
tckgen command would be invaluable for my research.
Best regards and happy new year,
