Hi Anastasia,<br><br>After an intial tracula pipeline procedure, I found some tracts were not successfully reconstructed. Their aparc+aseg looked fine to me. So I reran the trac-preproc -prior and trac-path with an option, &#39;init=1&#39; in a dmrirc file.<br>

<br> Now, the analysis&#39;s running well on some, but not the other. I&#39;ve got an error in trac-preproc -prior:<br><br>INFO: Rejected 536 streamlines for straying off mask<br>INFO: Rejected 36 streamlines for reversing direction<br>
