[Gate-users] How to detect some sources ?

[Tsukahara Tatsuya]

Hello dear Gate-Users,

I have installed vGate. And I'm trying to simulate of PET.
I set some sources in the world. I show this code of sources below.
Then, I detected only SOURCE1 and SOURCE3. SOURCE2 wasn't detected.
I tried some patterns of geometry, but I couldn't detect all sources.
I am reading the user's guide but I don't understand what parameter I
should change...
Please tell me some hints and solutions.

Thanks a lot.
