Dear All,

I am working on a programmableFilter in Paraview 5.6.1  
The input data is composed by some vtp(s) that are fed to the filter. I am having some trouble when i run my script with **mpiexec**.

The error message says: “vtkPointLocator No points to subdivide”. This only appears if the script is executed in parallel. I also tried using a pvtp as input, collecting here all vtp(s), but i get the same error.

Could anyone help me with that? I did not find many examples on the parallelization of the programmable filter.

Best Ragards

Dear all,  
after a bit of debugging, it seems that using the filter groupDatasets before the programmable filter is causing the problem.
