The point data arrays are probably ordered differently on separate blocks or there are different point data arrays on different blocks. My suggestion is to use a python programmable filter to remove the unneeded arrays or to reorder them.<div>

I'm trying to extract data along a streamline. I have a script that works fine in serial, but gives errors in parallel. I get the same errors if I use the GUI or if I run the script with pvbatch, so I don't think it's a problem with the script. The errors I get are:</div>
<div><br></div><div><div>ERROR: In /nv/hp25/bcolcord3/ParaView/VTK/Common/Core/vtkDataArray.cxx, line 474</div><div>vtkDoubleArray (0xd4058a00): The number of components do not match the number requested: 3 != 1</div><div>
<br></div><div>Warning: In /nv/hp25/bcolcord3/ParaView/VTK/Common/DataModel/vtkTable.cxx, line 421</div><div>vtkTable (0xd4634a60): Cannot assign this variant type to multi-component data array.</div></div><div><br></div>
<div>These errors occur when I do "writer.UpdatePipeline()" in the script, or "Save Data" in the GUI. Output is still produced, but the attached images show the problem. The streamline co-ordinates are OK, but the density along the streamline is not. </div>
