<div>Im working with optical simulations using LUT davis model, but i'm facing some problems in order to get the pixelID response from the simulation.<br>
</div>
<div><br>
</div>
<div>i.e :</div>
<div><br>
</div>
<div>I'm simulating a monolithic crystal associated with an array detector, but, i can't read any information in pixelID. It shows it's value ranging from -1-0, and containing all single events, as if it was a single element, but actually it was repeated in
the code.</div>
<div> <br>
</div>
<div>I've also noticed that if I use depth 2 ( to sum the pulse in the pixel using optical system) the singles tree shows no data. The tree appears and also all its leaves but no information is shown. I can only obtain data if using readout depth 0 or 1.</div>
<div><br>
</div>
<div>The surfaces crystal-apd apd-crystal were set as "Detector_LUT" and the crystal's surfaces were set to PolishedESR_LUT.</div>
<div><br>
</div>
<div><br>
</div>
<div>is there any configuration that i'm missing? how to solve this problem?<br>
