<div dir="ltr">Dear Gate users,<div><br></div><div>I am simulating an OpticalSystem in Gate. I need to set a threshold and an uphold to the digitizer. However, I found that no matter what value I set as optical photon energy threshold, this threshold does not work (all photon are detected even I set the threshold to an impossibly high value). Moreover, no matter what value I set as uphold, it will result in no detection of photon at all in the final projection output. I cannot understand this. Can anyone help me? Thank you in advance.</div>
