[Gate-users] Illegal application state </gate/source/addsource twogamma>

[Anastasios Gaitanis]

Dear all,

I am a beginner user of GATE v. 5.0 and I am trying to set up a source in the PET scanner.
When I put in my code the command /gate/source/addsource twogamma
the batch is interupted and the following message is shown:

Illegal application state </gate/source/addsource twogamma>
What I can do? Where is the wrong?

thanks in advance
