I am running a cylindricalPET employing GATE 2.1.0 with G4 6.2 p02. I have experienced that verbose information is continuously reported during simulation, such like:</DIV> <DIV> </DIV> <DIV>Pulse real time:<BR>32.2157 ms<BR>Pulse new time:<BR>32.2157 ms<BR>Difference (real - new time):<BR>211.364 ps<BR></DIV> <DIV>This seems to slow down the simulation significantly!</DIV> <DIV> </DIV> <DIV>I have tried to set all the possible verbose levels to zero, but it has no effect:</DIV> <DIV> </DIV> <DIV>/gate/digitizer/verbose 0<BR>/gate/digitizer/Singles/timeResolution/verbose 0<BR>/gate/digitizer/Singles/verbose 0 </DIV> <DIV> </DIV> <DIV>I have experienced that turning off the timeResolution process solves the problem. Unfortunately I need timeResolution...</DIV> <DIV> </DIV> <DIV>I have found that this problem was reported about a year ago by Dr. Jin Zhang at Stanford University Medical Center. I have contacted Jim and he reported the problem was not resolved yet. He suggested to use batch mode, I have tried, nothing changed.</DIV> <DIV> </DIV> <DIV>Has anybody any kind of idea how to elude this problem?</DIV> <DIV> </DIV> <DIV>Thank you,</DIV> <DIV> </DIV> <DIV>Tamas Bukki<BR>physicist, Ph.D<BR>tamas.bukki at mediso.hu</DIV> <DIV> </DIV> <DIV>Mediso Ltd.,  Hungary<BR><A href="http://www.mediso.com">www.mediso.com</A> </DIV></BODY></HTML>
