Dear MRtrix community,
I am in the process of analyzing the streamlines that I generated using tcksample. However, I would like to apply sift2 to apply weightings to the streamline and remove the ones below certain threshold. I couldn’t find an option to include weights in tcksample. I’d appreciate any guidance you might have on this matter.
Looks like some confusion around what each command is responsible for:
… analyzing the streamlines that I generated using
tcksample can’t “generate” streamlines; it’s only responsible for sampling quantitative values along the trajectories of pre-calculated streamlines.
… and remove the ones below certain threshold
This is a very different operation to what
tcksample does. See
I couldn’t find an option to include weights in
There’s no operation within
tcksample that would either be modulated by the availability of streamline weights, or have any effect on the streamline weights.
