Hi Hussain,
<div><br>
</div>
<div>Could you possibly include your .mac file? Two things to check would be to make sure to have defined attachCrystalSD with your scintillator, and make sure your scintillator is defined as a daughter of SPECThead.</div>

</div>
<div>Regards,</div>

</div>
<div>From first glance, it looks like you’re missing the readout module in the digitizer. Try that out and let me know.</div>
