[Paraview] running Paraview vis pvbatch with NO GUI - help?

[Utkarsh Ayachit]

Cynthia,

Have you had the a look at the ParaView Guide?
http://www.paraview.org/paraview-guide/
It explains the concepts of filters and the data analysis pipelines
used in ParaView.

So if I understand this correctly, you want to open a CSV file, apply
Table to Points filter and then save the result out
as a dataset that you can open later if needed without actually doing
any rendering?

If so something like the attached Python script will do the trick. I
generated that using Trace from the GUI, but then removed all the view
related components
since I don't care about those.

You can use the pvbatch or pvpython executable to run the Python
script without the GUI.

This is only needed if you are intending to rendering and you don't
have an X server running on your cluster.
