Hello VTMK users / developers,

I am trying to use the vmtkcenterlinegeometry script to determine curvature. 
The script appears to run and there are no error messages, but the resulting 
.vtp file has no data in it.

I looked up possible fixes to an error I had earlier (LengthArrayName not 
specified) and found a response to someone running ubuntu, so I added what I 
thought were the correct two lines into vmtkcenterlinegeometry.py but changed 
the parts in () to match what was in other lines of code (I am not familiar 
with Python so I'm winging it):

centerlineGeometry.SetLengthArrayName(self.LengthArrayName)
centerlineGeometry.SetTortuosityArrayName(self.TortuosityArrayName)

It prevented error messages but it's not actually creating anything now. Any 
other ideas on how to fix this? I am running vmtk 0.9.0 on Windows Vista.

Thanks,
Laura
