Visualize Multiple .TRK at once
Hi,
Question is mostly in the title, but I would like to visualize multiple .TRK at once. When I click Add Tracks and load a new .TRK, the old .TRK will disappear from view.
Thanks,
Steven

Simple solution is
http://trackvis.org/blog/tag/track_merge/
Note that the merged file will provide a different property tag for each track in the newly merged file, so you will be able to distinguish them when you view them with Surfice.

Or if you prefer Python

RE: Visualize Multiple .TRK at once
Dear experts, I am trying to load a merged track (I used
track_merge command to merge the three segments of the arcuate
fasciculus that i previously dissected in Trackvis). I got a merged
track as a result but when I load it in Surf Ice do not find
different property tag for each track, there is only one DATASETID.
When I open the merged track with Trackvis i can not find different
tracks neither (so I have my three segments merged as an only
track). Any idea of where could be the problem?
thanks in advance,
Diana López Barroso

Consider example data from here:
https://brain.labsolver.org/hcp_trk_atla...
https://pitt-my.sharepoint.com/personal/...
You can merge these two files with the command
track_merge CC.trk AC.trk AC_CC.trk
The two regions have the index 0 and 1, which you can view in Surfice by choosing the property name provided by track_merge ("DATASETID") and your preferred color scheme - here the AC is green and the CC is blue:
