Hi there!  
I am currently trying to make a selection and delete cells/particles on a dataset I have with 100 timesteps where the particles move. However I want to select the particles at the first time step and delete them from all the timesteps.  
ExtractBySelection does not work because it selects the right particles in one timestep but as the particles move in subsequent steps, they become unselected if they move beyond the selection by frustum. The same happens with Clipping.  
Appreciate the help!
