[Mrtrix-discussion] Facial Nerve Tractography

[Ivan Alvarez]

Hi Matthieu,

This mailing list has been largely superseded by a Google+ page here: 
https://plus.google.com/communities/111072048088633408015

Also, if you would like some advice from the community I would recommend 
including the following details in your post: 1) what exact structure 
are you attempting to track? A particular branch of the facial nerve, or 
the whole thing? 2) what method are you using? (tracking algorithm, 
seed/waypoint ROIs, location), 3) what dMRI acquisition are you using? 
(resolution, b values, etc.) and most importantly, 4) what makes you say 
the results are not convincing? in other words, what's going wrong?

Also, since you're writing here I'll guess you are using MRtrix2, rather 
than the newer version (https://github.com/jdtournier/mrtrix3), so it's 
worth pointing that out too. Some extra detail would make it easier for 
the experts to point you in the right direction. Good luck!

Kind regards,
Ivan Alvarez
