Visualizing whole tracks with significant segments from a fixel-based analysis

1

Hi all!

Does anyone happen to know how to visualise the rest of a streamline when a segment of it is found significant after applying the results of a fixel-based analysis (with fixel2tsf)?

For example, I have this significant difference in my groups here at p < .05:

And want to know if/where these streamlines might lead to.

I was thinking maybe by applying the maximum p-value from a .tsf file created with fixel2tsf to each whole track, but I haven’t been able to find a way to do this. If anyone has any tips that would be great!

Thank you,
Sophie

Hi Sophie,

If the ultimate goal is to determine the tracts that contain the significant fixels, one option might be to use TractSeg, and find the intersection of the TractSeg bundles with the significant fixels. The nice thing about this solution is that TractSeg bundles need minimal filtering to make them look pretty for subsequent visualisation :slight_smile:

Hope this helps!

Cheers,
Arkiev
