For verbose level, the best practise to see difference is to compare the output files.

Dear Gate people, I have a question regarding the spatial resolution in the GATE macro. If I include the lines: /gate/digitizer/Singles/insert spblurring /gate/digitizer/Singles/spblurring/setSpresolution 3.0 mm /gate/digitizer/Singles/spblurring/verbose 1 Then what is the energy of reference for this 3.0 mm value? For the energy blurring it is clear enough, because you include the line /gate/digitizer/Singles/blurring/setEnergyOfReference 140.5 keV Is the same energy used for the spatial blurring, or is there a standard value implemented in Gate? Also, what does the verbose setting do? What's the difference in setting the verbose to 0 or 1? Thanks alot in beforehand!
