<p class="MsoNormal">To Whom it May Concern,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I have been attempting to insert a rectangular phantom (test_phantom) into a cylindrical PET system, in order to more closely model the experiment we conducted.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I edited the benchPET.mac macro in the benchmark/benchPET directory so that instead of inserting a cylindrical phantom, I insert a box. I correspondingly changed the physics.mac and phantom.mac macros that are called from the benchPET.mac
macro.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Unfortunately, the program does not run. I crashes with an error ‘The region ‘test_phantom’ does not exist’ (l.623) in src/GatePhysicsList.cc.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Any suggestions?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Thanks in advance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
