Hi George,
<div><br>
</div>
<div>The error message is giving you a hint at what is wrong: it says that the volume does not exist and thus, it is ignoring the confine command. If you look at the voxelized source macro, you'll find the following line:</div>
<div><br>
</div>
<div>
<div>/gate/source/voxel_brain/gps/confine NULL</div>
</div>
<div><br>
</div>
<div>which is the source of this error (which by the way, in no way affects your simulation). The problem here is that the keyword NULL is used to unset the confine command, but somehow Gate looks for a volume called NULL and throws the error.</div>
<div><br>
</div>
<div>By default, a new source in Gate is not confined. So the confine command is unnecessary here. Simply comment it out of the macro and the error message will disappear.</div>
<div><br>
</div>
<div>Cheers!</div>

Dear Gate users,
<div><br>
</div>
<div>I use Gate <b>V6.2</b>. I tried to implement a voxelized phantom into my simulations. The file is an interfile. My implementation was based upon the example of Voxelized Phantoms. During the execution, I get an error not at the Phantom construction but
at the source construction. I would like to know what you suggest at this occasion. It is pretty bizarre to give the same file and to get two answers. Thank you in advance for your help.</div>
<div><br>

<div>Best regards,</div>
