Dear Paul,
<div class=""><br class="">
</div>
<div class="">have you tried accessing the componentID, volumeID, pixelID etc. stored in the root tree? These variables should enable you to figure out in which element of your system an event was registered.</div>

<div style="margin-top: 0px; margin-bottom: 0px;" class="">I am currently working on a cylindrical PET system with heterostructured scintillators. At first I am designing a one block detector and want to get a proper readout done before creating a whole scanner.</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Goal of this is to simulate a couple of materials and calculate their CTRs. My problem is that eventhough I assigned the two different layers as separate sensitive detectors, I only get one root tree
 for the energy deposited in the singles tree.<span class="Apple-converted-space"> </span><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">I've tried it with one crystal for each layer, or with just one crystal for both layers. I've tried the DoseActor, but the created File seems to have as many entries as I define in the macro with the
 variable z in "/setResolution x y z", eventhough I dont have that many hits or singles. So I don't think thats a proper way to get the deposited energy for each layer.</div>
