<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear Gate-users,<br>
<br>
I'm just about to start working with optical photons in Gate and have gotten a test script for trying this feature. However, when running I get the error message below:<br>
<br>
<br>
***** COMMAND NOT FOUND </gate/micropixels/surfaces/name glasslayer_micropixels> *****<br>
<br>
I can manually within Gate see that "surfaces" is not an enabled feature of any created geometry. I've followed the User guide and made sure that GATE_USE_OPTICAL is set to "ON", recompiled and re-run the Gate-installation (make install). However, I still seem
to get this issue.<br>
<br>
I'm working with the following package versions:<br>
<br>
Root version is 5.34/22<br>
<br>
Geant4 version is 10.0.3<br>
<br>
CMake version 2.8.12.2<br>
<br>
CLHEP version is 2.2.0.3<br>
<br>
Gate version is 7.0<br>
<div><br>
Does anyone know what I have to do to enable surface and optical photon options? Does anyone know how to proceed from the above?<br>
<br>
Thanks in advance for your help.<br>
<br>
Best regards,<br>
<br>
