I am using the Postprocessing for Turbomachinery,I download the code from:http://sourceforge.net/projects/turbopost/,but i don't know how to use them in paraFoam.
I try the turbofilter.py in the turbevtk.And I use the ProgrammableFilter,the script is:

import sys
sys.path.insert(0 ,"/home/username/python/vtk/")
import turbofilter as filter

## Input format default value is openfoam
## Set input format to numeca
filter.setInputFormat("numeca")
## omega default value is 0.0
filter.omega = 2*filter.math.pi*28160.0/60.0
## Calculate only Cm, Cr and Cu
filter.setTrue(["Cm", "Cr", "Cu","Ma", "MaRel"])
## All variables were calculated
# filter.setAllTrue()
## run calculation
filter.run(self)

But I get the error:

File "<string>", line 2
if not file:///home/pjc/OpenFOAM/pjc-1.6-ext/turbopost-turbovtk/src/turbofilter.py
^
SyntaxError: invalid syntax

AttributeError: 'NoneType' object has no attribute 'GetTuple3'

I have also try the python shell in paraview,it doesn't work.

Who can tell me the step of using python script in paraview?thanks.
