<p dir="ltr">Dear all,<br>
I'm enthusiastic about mrtrix. Is there any hands on course / bootcamp on it?<br>
thank you</p>

<p dir="ltr">I don't think that can be done - the tensor tracking algorithm in MRtrix takes the raw DWI as input, so that it can do interpolation on the raw DW signals. I'm guessing the tensor images produced by DTI-TK have been non-linearly registered, so there's no way of using the original DWI. One potential way around it would be to generate some fake DWI signals from the DTI-TK output and feed that to streamtrack. Sounds a little too much of a hack for comfort though, not sure I'd recommend that - mind you, I wouldn't recommend tensor tracking in the first place either...</p>
<p dir="ltr">Another approach worth exploring would be do the tracking in native space and warp the tracks to the other space afterwards, using the approach outlined here: <br>

I'm sure that idea could be adapted for DTI-TK too.</p>

<p dir="ltr">I have a doubt, is possible to convert tensor images of DTI-TK to do the tractography with MRtrix? Thanks in advance.</p>
