<div dir="ltr">Hi Donald,<br><br>Thank for your help. To obtain the first comparisons I will use this trick, but in the future I would like to coregister the HARDI data in a template space. I'll try to find more information about this topic.<br>

We have methods to do this, but they haven't been released yet. If what you want to do is coregister tractography results that were derived in each subject's native space, then you can do it using this trick: <a href="http://www.brain.org.au/software/mrtrix/faq.html#normalise_tracks" target="_blank">http://www.brain.org.au/software/mrtrix/faq.html#normalise_tracks</a></div>
