Dear Gate users,<br><br>I am trying to simulate a simple scanner with scintillator. When I input the commands related to surface definition the following message appears: COMMAND NOT FOUND </gate/pixel/surfaces/name pmtsurface>. Is there any thing that should be considered before surface definition which I have missed? (I have installed GATE V.6.1 on Ubuntu 10.4).<br>
I do appreciate any suggestion.<br clear="all"><br>-- <br><div> </div>
