Hi all,

 

I've been exploring the commandline tools for track_vis and I am trying to create a track between 2 rois. When run via command line with the command below I do not get any results (0 fibers). However, if I create the track within the TrackVis GUI I get 20 plus fibers. Any thoughts, is my command line call incorrect?

 

track_vis dti.trk -roi warped_Atlas_GM_Visual_cortex_V5_R_bin.nii 0.5 2 -roi2 warped_functional_antInsula_zstat4_tonic_mask.nii 0.5 2 -o output_track.trk -ov outputtrack.nii -rois warped_Atlas_GM_Visual_cortex_V5_R_bin.nii 0.5 warped_functional_antInsula_zstat4_tonic_mask.nii 0.5

 

Thanks,

 

-James

Do the 20+ tracks you see in TrackVis only touch the edge of at least one of the ROIs? The track_vis program was written a long time ago and may use a different approach for hit test.

Best,
