How to save the generated streamlines

Dear Experts,

I followed the script on MRTRIX3 to analyze the data and displayed the results with streamlines(FBA_pipline). At this time, I hope to save the streamlines for further analysis. What should I do?

I want to export fiber bundles in .tck or .vtk format, the effect is similar to the type that Mito publishes on brain(doi:10.1093/brain/awx355).

I would be very grateful if you could help me solve this problem.


I think what you’re asking is answered in the second part of this wiki post…? Let us know if that doesn’t answer your question!

Thank you for your reply. I did the second part of the wiki you gave, and got the streamlines in mrtrix3. Now I hope to export it(in ‘.tck’ or ‘.vtk’) for further analysis. Please give me some advice

Well, the streamlines are already in .tck format – what you have now is an additional .tsf file that you can use to threshold and/or colour the streamlines in mrview. If you’re looking to export these to vtk format for display in other packages, I’m afraid we don’t have the tools to do this currently (others might correct me if I’m wrong here). But assuming you’re happy to display them in mrview, then you can simply load the original streamlines, and select your newly-generated tsf file in the Thresholds selection.

Hello, thank you for your reply. I really need to export the streamlines after setting the threshold. Cause, it’s hard for me to determine the white matter area corresponding to these streamlines, so I would like to export them for further analysis. Thank you!
