[Gate-users] Rayleigh exception when simulating optical photons

[Esteban Venialgo]

Dear Gate Users,

I get this error when I enable the "OpticalRayleigh" process:
/gate/physics/addProcess OpticalRayleigh


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

  * G4Exception : ProcMan201
    issued by : G4VProcess::SubtractNumberOfInteractionLengthLeft()
    Negative currentInteractionLength for OpticalRayleigh
  * Event Must Be Aborted **
  * -------- EEEE -------- G4Exception-END --------- EEEE -------



I tried to run the same simulation on Gate6.2 and Gate7.0


Gate6.2: geant4-09-05-patch-01

                root 5.26

                clhep 2.1.1.0

                CentOS release 5.10


Gate7.0:  geant4-09-06-patch-03

                 root 5.26

                 clhep 2.1.3.1

                 CentOS release 5.10



Have someone had the same problem ??


              Esteban,
