Extract and visualize tracks like tck2connectome


I would like to visualize the tracks that have been counted in my connectivity matrix.
I have a set of 100 regions and use the -assignment_reverse parameter.
Is it possible to extract those tracks with tckedit or anything similar with the same criteria that tck2connectome use ?

Thank you,

I’ve found a way to do this:

  • compute tck2connectome with the -out assignments option
  • and then compute connectome2tck

This way I get the tracks between each pairs of regions as independent tck file and can visualize then in mrview.

Hi Céline,

… and use the -assignment_reverse parameter.

Is there any particular justification for using this over the default? It’s kind of there to demonstrate the fact that there is myriad possibilities for mechanisms to assign streamlines to a parcellation image. If you have big fat parcels that project well into the white matter (e.g. AAL) then it’ll probably do OK, but it’s not something that I’d typically advocate using unless there’s a good a priori reason for doing so.


Hi Rob,

I am working on ferrets and my parcellation is a self-made ribbon between the GM and WM with a random parcellation. What would you rather recommend ?
