<p class="MsoNormal">First thing first. The code inside the Programmable Filter script runs in a context in which it is aware of VTK only and not ParaView, so you cannot use paraview.simple module functions such as Clip. Instead, you would need to use a VTK-equivalent.
In this case, you would use vtkClipDataSet:<o:p></o:p></p>
