<br>
Did you try a short simulation with your macro and did you confirm that the source is not properly confined? (For example, by looking at the source position distribution in the Root output.)<br>
<br>
The reason I'm asking is that, in the past, I've found limitations in the Geant4 visualization code. For example, see this thread from the mailing list: <a href="http://article.gmane.org/gmane.comp.science.opengate.user/3109/match=source+visualize" target="_blank">http://article.gmane.org/gmane.comp.science.opengate.user/3109/match=source+visualize</a><br>
<br>
My first instinct is that this may be related.<br>

Hello!<br>
<br>
I'm trying to confine a source to a particular phantom geometry, but cannot get it to work properly. Part of the source spills out outside the confinement volume. Below are codes for the phantom + source and a visualization image where you can see the issue.<br>
<br>
Any ideas how to solve this?<br>
<br>
Thank you in advance! Sincerely,<br>
Ida<br>
