paraview particle tracer

Hello there,
I am encountering errors when I use the particletracer filter on a vtr time series in paraview version 5.11.1. The error looks like this
ERROR: In vtkStreamingDemandDrivenPipeline.cxx, line 878
vtkPVPostFilterExecutive (0xf4e1920): The update extent specified in the information for output port 0 on algorithm vtkPVPostFilter (0xf3d90c0) is 0 96 0 76 0 22, which is outside the whole extent 1 1 0 76 0 22.

My data is a sequence of vtr datasets. They contain separate U,V, and W velocity components. I use the calculator to construct a velocity vector. I then extract a subset ( x = 1 plane) of the data to use as a seed for the particle tracer. The input of the particle tracer is the calculator output. The seed is the extract subset filter output. Executing the pipeline gives the error above.

I am running this on one of the HPC systems at TACC, single node no parallelism (small data). I can run the pipeline without error on my laptop ( god I know that sounds bad, sorry) so I think I am using the filters correctly. I even copied the state file from my laptop to the HPC system to no avail. It still fails on the HPC system. Any ideas how I can get this to work on the HPC system? I have some large data in the wings.

Best Regards,
Dave

never mind. I figured it out. It was basically a difference between 5.11.0 and 5.11.1. I fixed it by using a source object as the seed (plane) rather than a subset of the whole data.

thanks,
Dave
