Hello, I am thinking that a commercial software called Avizo could do auto skeleton and output the trajectory as mv3d (MicroVisu3D) file

mv3d header looks like this

```auto
# MicroVisu3D file
# Number of lines 1
# Number of points xxx
# Number of inter. 0
#
# No x y z d
#

```

Could I know if there is any similar function in 3D slicer?

Best regards
