I’m doing some tests with the seeding options in
tckgen. First I used the
-seed_dynamic and it worked OK, then I wanted to compare the outputs between
seed_sphere. The second one is faster than the first one, but my doubt is why, if I’m setting a seed region (in either case), do I obtain some tracks that born in other regions? I thought that I only could obtain tracks from the seeding point. I attached a screenshot to make it clear.
In the next figure you can see: the T1 image, the roi image (with colourmap hot), the node image and the connectome whose tracts were generated with the seed_sphere option.
