[Gate-users] Help - GATE confinement warning

[Sowmiya Raj Thirumalai]

Hi All,

  I am new to GATE. I tried adding NEMA 2 phantom (from examples in GATE)
to the PET cylindrical system. During the simulation, I am getting the
following warning message. Could anyone please tell me what the problem is?

  I am attaching my macro file and the visualization for reference.

Message:

*** This is just a warning message. ***
-------- WWWW -------- G4Exception-END --------- WWWW -------


-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : G4GPS001
      issued by : G4SPSPosDistribution::GenerateOne()
LoopCount = 100000
Either the source distribution >> confinement
or any confining volume may not overlap with
the source distribution or any confining volumes
may not exist

If you have set confine then this will be ignored
for this event.

Thanks & Regards
Sowmiya
