Next, as the xdmf file gets its data from binary files in a separate directory, I entered the file path to those files in the file location field (i.e. <path>/NeptuneData_2015-07-28/0000/f*.bin). I think this is where the plugin will get its data (this may be where the problem is).<br><br></div>4.

<p class="MsoNormal">I've been working with spatio-temporal data stored in an xdmf file. I found that ParaView doesn't handle parallel processing of this file well, so I thought I would use the SpatioTemporalParallelism plugin to partition the data better.
I chose the Parallel Image Data Writer to write to a .pvti before using the plugin to export state. Once the python script was generated, and I tried running it with pvbatch, I got the following error message:<u></u><u></u></p>
