@fred,

Regarding your code, there are few things you need to change.

1. You need to install the `pandas` Python library or module. To do this, execute the following line in the Python Interactor: `slicer.util.pip_install('pandas')` [[1](https://discourse.slicer.org/t/install-python-library-with-extension/10110)]

2. Then Import the `pandas` module by executing `import pandas` also in the Python Interactor

Now you can enter the code above but, keep in mind that some variables may not be the same as you expect. For instance;

1. `modelNode = slicer.util.getNode("VTK Output File")` you may have named the output file to something other than **VTK Output File**

2. `slicer.util.arrayFromModelPointData(modelNode,"Absolute_to_BBCJG_vtkMRMLModelNodeF")` I am not sure what `Absolute_to_BBCJG_vtkMRMLModelNodeF` is but you may need to change this to one of the variables in the VTK structure, such as: `PointToPointVector` or `PointToPointAlongX` and so on…

3. Finally, make sure you have the correct path here `pandas.DataFrame(distances).to_csv(r"~/Desktop/Model/data.csv", index=False)`

Also, I had to change all of the single quotations `'` to double `"`, I think this is a Windows/Linux thing. I am using a Windows!

Another trick that may work for you is to inspect the **VTK Output File** manually. You can always save the file as a ASCii or decompressed version of the file and open it with a text reader.
