Save a tree of centerline curves to json files using Python

[ruili]

Hello,

I have created a tree of centerline curves using functions from the “Extract Centerline” module, and now I want to save the curves in a file structure that can reflect the tree structure. In Slicer, I can do this by right click the stem curve → “Export to file…” → Check all the options.

This will save my curves in a folder structure that looks like this:

Now I wonder if there is a python command to do this easily as well? It will be great to add this to my automatic code that runs the centerline extraction.

Many thanks!
