Hi Margaret,<br><br>That is sure is that you will obtain your energy window and maybe this will speed up your simulation, but not significantly (only because there will be less Events to write on your disk I think ... ).<br>

<div><font face="arial">Hi all,</font></div> <div><font face="arial"></font> </div> <div><font face="arial">I am simulating Tc source for SPECT system and I would like to model an energy window. Is it correct to use these lines of command:
</font></div> <div><font face="arial"></font> </div><font size="2"> <div><font face="arial">/gate/digitizer/Singles/insert thresholder</font></div> <div><font face="arial">/gate/digitizer/Singles/thresholder/setThreshold 126. keV
</font></div> <div><font face="arial">/gate/digitizer/Singles/insert upholder</font></div> <div><font face="arial">/gate/digitizer/Singles/upholder/setUphold 154. keV</font></div></font> <div><font face="arial"></font>
</div> <div><font face="arial"> or they are only used to speed up the simulation?</font></div> <div><font face="arial"></font> </div> <div><font face="arial">Thanks in advance.</font></div><span class="sg"> <div><font face="arial">
