Hi,

I am trying to perform centerline extraction and quantifiaction using the slicer [VMTK extension](https://github.com/vmtk/SlicerExtension-VMTK).  
Using the feature that auto-detects the end-points of the centerline, I want to perform the computation on a batch of surfaces contained in a folder automatically using python.  
Essentially, I want to be able to run the [following script](https://github.com/vmtk/SlicerExtension-VMTK/blob/master/ExtractCenterline/ExtractCenterline.py) over a set of surfaces telling slicer that the end-points should be auto-detected.  
Any pointers on how to go about this?

Thanks in advance,
