<br>
Have you defined your system as sensitive detectors? If not, get a look on this link, on how to define detectors as a sensitive detectors: http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.2:Attaching_the_sensitive_detectors<br>
<br>
Sincerely,<br>

<br>
</div>
<div>
<div dir="ltr">
<div>I am trying to build a very simple recreation of a scintillator, but I'm running into some problems. I'm starting with optical photons from inside the crystal so I don't have to worry about scintillating events, but I'm unable to get any of the photons
to actually leave the crystal... even out of the ends. I've followed the instructions for optical systems pretty closely, but I'm not making any headway. I've also tried to define surfaces, but it's giving me a "command does not exist" feedback and aborts
the simulation. I also made sure that my GATE_USE_OPTICAL in on the the ccmake and the cc file. I haven't restarted the computer since, so that may be the problem. But if anyone out there thinks of anything that might help, I would greatly appreciate it.<br>

Many cheers,<br clear="all">
