TypeError with pointlist

[Hannes]

Dear vmtk-community,

my goal is to compute the centerline for an artery given as Surface Mesh (".vtk").

I used -seedselector pointlist -sourcepoints 48.478 32.2861 2.267 -targetpoints 73.062 53.0041 -132.212 and computed the centerline.

I get a TypeError:

Traceback (most recent call last):

  File "C:\ProgramData\Anaconda3\envs\venv\lib\site-packages\vmtk\pypeserver.py", line 46, in RunPypeProcess

    pipe.Execute()

  File "C:\ProgramData\Anaconda3\envs\venv\lib\site-packages\vmtk\pype.py", line 324, in Execute

    scriptObject.Execute()

  File "C:\ProgramData\Anaconda3\envs\venv\lib\site-packages\vmtk\vmtkcenterlines.py", line 595, in Execute

    self.SeedSelector.Execute()

  File "C:\ProgramData\Anaconda3\envs\venv\lib\site-packages\vmtk\vmtkcenterlines.py", line 128, in Execute

    for i in range(len(self.SourcePoints)/3):

TypeError: 'float' object cannot be interpreted as an integer

How can I fix this error?

Thanks,

Hannes

Hello Hannes,

It's a bug, I think leftover from years ago when VMTK switched from Python 2 to 3.  It was fixed in the original source code a couple years ago, but apparently not in the conda package.  Fortunately, it should be easy to fix.  You can see the changes in this commit.  Just find the file (vmtkcenterlines.py) and line (128, and also 133) where the error occurs, and add another division symbol.
