Hi Dan,<div><br></div><div>There's quite a few options here. You can export the track data using the -ascii option of <a href="http://www.brain.org.au/software/mrtrix/commands/track_info.html">track_info</a> (produces one text file per track), or the <a href="http://www.brain.org.au/software/mrtrix/commands/tracks2vtk.html">tracks2vtk</a> command (produces one file in VTK format). You can also load the track data into Matlab using the 'read_mrtrix_tracks.m' command included in the matlab folder of the latest release. Otherwise, the format itself is now described in the documentation: <a href="http://www.brain.org.au/software/mrtrix/appendix/mrtrix.html">http://www.brain.org.au/software/mrtrix/appendix/mrtrix.html</a>.</div>
<div><br></div><div>Hope that helps.</div><div>Cheers,</div><div><br></div><div>Donald.</div><div><br></div><div><br><div class="gmail_quote">On 25 February 2012 03:49, Dan Wu <span dir="ltr"><<a href="mailto:dwu18@jhmi.edu">dwu18@jhmi.edu</a>></span> wrote:<br>

<div style="direction:ltr;font-size:10pt;font-family:Tahoma">Hello All,
<div><br>
</div>
<div>I would like to extract the fibers that I tracked using mrtrix and converts them to other formats so that I could visualize them in 3D in some other softwares (I primarily using DtiStudio). Can I know the organization of .tck files? Or does mrtrix have
function to visualize fibers in 3D?)</div>
<div><br>
</div>
<div>And two side questions: 1) If using SD_STREAM method, is that only one fiber will be tracked out of one voxel (or the interpolated voxel)? 2) will you implement DT_PROB method in the future?</div>
<div><br>
</div>
<div>Thanks a lot!</div>
<div><br>
</div>
<div>Regards,</div>
