I'm doing tractography of the dentatorubrothalamic on a single subject's data. I'm having a strange issue where when I do autotracking of the right and left tracts, each single tract runs along an ipsilateral path (90% of the fibers). Normally, it should be the other way around as the majority of the fibers from this tract decussate in the red nucleus. Is it possible that this autotrack reconstruction tracks the the dentato-rubro part correctly but then switches to the ipsilateral rubro-thalamo-cortical part afterwards? When displaying both sides, the overall results seem fine.
I've sent the src and fib files to the Dropbox (lesion is known).
Here is also a quick screenshot of what I mean
