[Gate-users] FWHM without feeding during SPECT simulating

Dear gate users,

I need your kind cooperation in a problem that I asked about three days ago
but none has answered.

I am calculating energy resolution (FWHM), to validate the gamma camera.
The way I am preceding is, I used digitizer module and saved it's output in
ASCII format, from single.dat ASCII file,I extracted energy deposited and
calculated FWHM (energy resolution), this value of energy resolution is
same which I set in script as ;

/gate/digitizer/Singles/blurring/setResolution 0.10

My question is how can we calculate energy resolution without pre-setting
it's value in script (as above) to validate the camera.

I hope someone will guide me
Thank you
