[Paraview] Writing files from pvbatch

[houssen]

Hello,

I have a filter which writes some ACSII text files. I use it from a 
python script.
When I run the script from paraview (paraview 
--script=/path/to/script), ASCII files are created.
When I run the script from pvbatch (pvbatch /path/to/script), ASCII 
files are NOT created : why is that ?

Thanks,

Franck
