Hi Peter,<div><br></div><div>There is currently no probabilistic tensor tracking algorithm in MRtrix, but there is a deterministic FOD-based tracking algorithm (although I would always recommend the probabilistic version of the algorithm, for reasons outlined in <a href="http://onlinelibrary.wiley.com/doi/10.1002/ima.22005/abstract">this paper</a>). Simply use the SD_STREAM algorithm in streamtrack:</div>

Hi Donald,<br>
<br>
that worked just fine, thank you! I have another question. The
probabilistic tracking is only explained for the CSD data. Is it
also possible to run it directly on the tensor data? And is it also
working the other way round, meaning is there a deterministic
tracking for the CSD data?<br>
<br>
Best,<br>

everybody,<br>
<br>
I am looking at the mrtrix tracking capabilities at the
moment and I wondered if there is a way to convert the .tck
files to the commonly used vtk ascii file format.<br>
