Hi Devin,
<div class=""><br class="">
</div>
<div class="">I’m not sure I understand what you’re trying to do and what failed to work. Can you provide more details?</div>
<div class=""><br class="">
</div>
<div class="">Also, did you attach a crystalSD to your plates, as outlined here: <a href="http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Attaching_the_sensitive_detectors#The_crystalSD" class="">http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Attaching_the_sensitive_detectors#The_crystalSD</a></div>

<br class="">
I am simulating a PET system with two plates. I would like to use the takeEnergyCentroid option for the digitizer's readout. However, I need to attach a volume to a 'crystal' of a system (according to the error message I keep getting). Thus a PETscanner system
 cannot work since it uses level1-4 and layers for system attachment. The I tried a cylindricalPET system with a ring repeater of 2, and that also didn't work. Interestingly, cylindricalPET works for a 4+ plate ring system, but no singles or coincidences in
 the output for 2-3 plates (with only the ring repeat number changed). Can anyone offer any insight as to what I should do?<br class="">
