No it is not forbidden but if you have defined only 3 depths in your
cylindricalPET (for example : the cylindricalPET, rsectors and crystals),
depth number 5 does not exist. I am not sure of that and I can't verify it
as I am not at work ;-) But if my memory is good, I already had this
problem.

If the problem persists, send your macro.
Cheers,
Simon

because when i choose this value, the simulation doesn't finish, it stops
