Hi,

I am trying my first fast simulation..I am using the /macro/scrut/simfast.C macro...
I have my own decay file, and when I try to run the simulation it goes fine umtil a point...then it crashes..What i get is this:

Loading VGM libraries ...
Loading g4root library ...
Loading libraries ... finished
Error in <TGeoManager::CloseGeometry>: you MUST call SetTopVolume() first !
Error in <TGeoManager::CloseGeometry>: you MUST call SetTopVolume() first !

-------- EEEE ------- G4Exception-START -------- EEEE -------

*** ExceptionHandler is not defined ***
*** G4Exception : G4Root_F001
issued by : TG4RootDetectorConstruction::TG4RootDetectorConstruction
Cannot create TG4RootDetectorConstruction without closed ROOT geometry !
*** Fatal Exception ***
-------- EEEE -------- G4Exception-END --------- EEEE -------


*** G4Exception: Aborting execution ***


Any help???I am doing something wrong but I don't know what...Any ideas???

Thanks
