Hello everyone, 
I run a simulation of the benchmarks (benchSPECT) . I want to get the spectra of energy resolution and spatial resolution . What is the command to bring the two spectra. Thanks

Hello Germano Russo,

thank you very much for your pull-request, it has been merged (develop
branch). I think a lot of users will be happy to see IAEA phase space now
corrected in Gate.

More details : https://github.com/OpenGATE/Gate/pull/34

Sincerely,
David
