Hi David, I'm not sure how it works with structured grids but with vtkUniformGrids (i.e. vtkImageData with blanking) the VTK readers and writers really just produce vtkImageData and the blanking is ignored. It may be the same with the XML structured grid files. My suggestion would be to look at the vtkImageDataToUniformGrid class in VTK and try doing a similar thing in ParaView using the Python Programmable filter.
