Greg,
sorry if I did not explain fully. After reading your data, it is the active
source. if you instantiate a ProgrammableFilter (PF), it takes wake_out as its
input. But you can also set it explicitly as the source.
inside the PF, you have VTK objects, so you can use VTK methods. Here is a
script that works for me. The last point is to manually create a spreadsheet,
because I just don't find a python command for it.
I load this as "paraview --script=script.py" and it scales the data just fine.
