The most straightforward way to use QuickBundlesX in DIPY (and this is what Horizon is calling internally) is by calling

from dipy.segment.clustering import qbx_and_merge

clusters = qbx_and_merge(streamlines, [40, 30, 25, 20, thr])

Where thr is the last threshold from 5-15.

This function is calling set_number_of_points to force all streamlines to have the same number of points and then starts QuickBundlesX (a dynamic version of QuickBundles that builds clustering hierarchies).

The thresholds are in mm in world coordinates.

We need a tutorial and an interface for this.
