Hi folks -</div>

I am new to Paraview and even newer to scripting with Python for Paraview (though at least, I am not new to programming!). I have a need to run Paraview on our HPC cluster here at the University of Arizona, and I need it to run ‘headless’ - I desire no GUI
output at all, but to process & filter an image series and create output, to be read into a local Paraview instance later. </div>

Here’s a few details, and my questions – the way I am going about this, I run Paraview normally, start a trace to create a python script, read in my image series and process it, then save the script. I then upload the script and data to our HPC. That all
works great! However, I run into trouble fully understanding how to manipulate the DATA vs. the RENDERING of what I ultimately would like to save to disk, to read into the Paraview GUI later, off line form the HPC cluster.</div>

So, firstly – If I read in a csv series of images, one image/file per moment in time, when I run a filter, the filter should run on the entire series, correct? But when I do this and then try to save the data – in this case, a series of table to points calculations,
it only saves the last one. Ideally, I’d like to save an animation and save the data, but WITHOUT calling on the GUI / rendering aspects of Paraview. Is this possible, and if so, how do I go about it? </div>

sounds like what I want, but how do I go about determining if the version of Paraview on my system ~s~ built is this manner, and if indeed it is, how do I script in Python to take advantage of that?</span></font></div>
