Hi Sal - I'm cc-ing the list since this is of general interest.
In 5.2 there's also a path.pd.trk file in the tracula output directory, which contains all the sample splines that were added up to create the probabilistic distribution in path.pd.nii.gz. The .trk format can be displayed in freeview or trackvis. These are still not like the pretty streamlines that you see visualized in deterministic tractography tools, simply b/c they haven't been smoothed.
Hope this helps, a.y

Dear Anastasia,
Is there a way to display the merged_avg33_mni_flt.mgz file as a set of streamlines, rather than the clay appearing structures generated by using freeview -tv /merged_avg33_mni_flt.mgz ? I ask primarily because my collaborators in surgery and neurology are becoming increasingly used to DTI fiber tracking images that give the appearance of multiple fibers (I recognize that the modeling of white matter tracts using probabilities does not support delineation of specific individual fibers, however, I think I am having a hard time even introducing collaborators to the DTI data generated by Tracula due to the unusual appearance of its output).
Thank you for your time and consideration.
Best wishes,
Sal
