[Paraview] Getting line data into Paraview 3.10.0

[Lester Anderson]

Hello

I am having problems getting line data into Paraview like below:

I did try the script:

import os
import string

def insertNextCell():
  nextpoly = vtk.vtkPolyLine()
  nextpoly.GetPointIds().DeepCopy(segments)
  cells.InsertNextCell(nextpoly)

filename = os.path.normcase("C:\temp\rifts_gmt.txt")
f = open(filename)

pdo = self.GetPolyDataOutput()

pts = vtk.vtkPoints()

#an array for the fault information
segmentNames = vtk.vtkStringArray()
segmentNames.SetName("Fault Information")
segmentNames.SetNumberOfComponents(1)

cells = vtk.vtkCellArray()
segments = vtk.vtkIdList()

#traverse file
for line in f:
  if line.startswith(">"):
    #when you find a new fault
    #save the one you just finished
    if segments.GetNumberOfIds() != 0:
      insertNextCell()
      segments = vtk.vtkIdList()
    segmentNames.InsertNextValue(line)
  else:
    #otherwise just keep remembering coordinates
    x,y = [float(n) for n in line.strip().split()[:2]]
    id = pts.InsertNextPoint(x,y,0)
    segments.InsertNextId(id)
f.close()

if segments.GetNumberOfIds()>0:
  #don't forget the last fault in progress
  insertNextCell()

pdo.SetPoints(pts)
pdo.SetLines(cells)
pdo.GetCellData().AddArray(segmentNames)
- this runs as a programmable source but only gives an error:
Traceback (most recent call last):
  File "<string>", line 24, in <module>
  File "<string>", line 11, in RequestData
IOError: [Errno 22] invalid mode ('r') or filename: 'c:\temp\rifts_gmt.txt'. 

I am working on Windows 7.
Any ideas?
Cheers
Lester
