I used the ASCII output instead of root output There are some problems after the simulation. The simulation lasted about half an hour.   1. There is only one row in gateSingles.dat and only two rows in GateHits.dat. I think there should be more data that chould be detected.     the output in gateSingles.dat are :     -842150451 -842150451 -1 0.000e+000 0.000e+000 0.000e+000 0 0 0 2.45800536085627130000000e-004 1.097e-001 2.009e+002 -8.443e+000 -1.025e+002 -842150451 -842150451 -842150451 -842150451 NULL NULL        the output in gateHits.dat are :   -842150451 -842150451 -842150451 -842150451 0 0 0 2.45800536085627130000000e-004 3.316e-002 4.364e+000 1.994e+002 -8.609e+000 -1.025e+002 22 1 0 -842150451 -842150451 -842150451 LowEnPhotoElec   -842150451 -842150451 -842150451 -842150451 0 0 0 2.45800536109077660000000e-004 6.708e-002 3.513e-002 1.994e+002 -8.609e+000 -1.025e+002 11 2 1 -842150451 -842150451 -842150451 eIoni      I don't know how to interpret these data. Why did all the IDs euqal -842150451 ?     2. The screen shows             the user simulation time = 958.61             real simulation time =0             system simulation time =0.563     what's the difference between these three simulation time? and I think there must be something wrong here, because real simulation time equals 0 .   3. In addition, I have a question about the time management. Are there any relationship between the geometry moving time and the time slice at the end? They are the same in the benchmarkSPECT.     Thanks,   Dan <hr />Express yourself instantly with MSN Messenger! <a href='http://clk.atdmt.com/AVE/go/onm00200471ave/direct/01/' target='_new'>MSN Messenger</a></body> </html>
