Good morning,
I would like to know if you have found a solution for my problem.
With the header of another subject I don't have problem but obviously the final output doesn't match the T1 image.
Could you give me some suggestions or help, please?

Thank you for your availability,
Marina

Hi,

I think that some of your seed points are outside the diffusion image volume. I will update the code to deal with this.
