Hello,

I started to use the VMTK took and I don’t understand.  
In my VTMK the only package I see relevant to centerlines are Extract centerlines.  
I don’t have the centerlines computation.  
is it the same? why I don’t have the same packages inside the VMTK tool?

In the `SlicerVMTK` extension, `Extract centerline` is the only module that computes centerlines.

Since you mentioned _Extract centerlines_, I assume that you are indeed referring to the `SlicerVMTK` extension.

You already have the `Extract centerline` module for that.
