Hi Anastasia,
I'll rerun all steps changing the Z gradient with *(-1). Thanks and I'll write
with the results. Best,
Fernando

Hi Fernando - I looked at your data and changing the sign of the z
coordinate in your gradient table gave me eigenvectors that looked fine in
both fslview and freeview. Why you would get eigenvectors that look
different in freeview and fslview before flipping z but not after is still

Hi Fernando - Thanks for uploading your data. Looking at the primary
directions from tensor fit on the data that you sent me (see screenshot),
they seem to be off by a 90 degree angle from what you'd expect them. This
means that your gradient table is probably off as well.
Hope this helps,
Hi Fernando - Thank you for your kind words. You can indeed try the reinit
option as Christofer suggested when one of the pathways looks like a
single curve and not like a volume.
However, because some of your other pathways in the screenshots look a bit
funky too, I would also check that
