pyAFQ_tractometry: Where is the streamlines.json equivalent?

[dkp]

To use AFQ-Browser or AFQ-Insight, I need an output file corresponding to streamlines.json as described here: https://yeatmanlab.github.io/AFQ-Browser/dataformat.html Unfortunately, I am not even sure what files I might be able to use to build it manually. Can you provide any guidance?

Thank you,

Dianne
