> Hi all, did anyone try to define the SPECT collimator using the parametrized collimator approach? I followed the docs example with parallelbeam collimator and I got the error saying that material for ,,side hole 1” was not defined. I couldnt find anything about this “side hole 1” and how to define its material. 
> Thank you for any advice.
