Hi again,<div><br></div><div>Just to follow up on that, there is a slightly roundabout way of displaying the tracks in 3D in MRView: load an image, and load the tracks in the tractography sidebar. Untick the 'Lock to Image Axes' option in the View menu, and untick the 'crop to slab' option in the sidebar. You can then rotate the projection by holding down the Ctrl key while dragging with the mouse, holding down the left mouse button to rotate in-plane, and the middle button to rotate out-of-plane. </div>

You can export the track data using the -ascii option of <a href="http://www.brain.org.au/software/mrtrix/commands/track_info.html" target="_blank">track_info</a> (produces one text file per track), or the <a href="http://www.brain.org.au/software/mrtrix/commands/tracks2vtk.html" target="_blank">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" target="_blank">http://www.brain.org.au/software/mrtrix/appendix/mrtrix.html</a>.</div>

<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>
<div><br>
