[Gate-users] Error with voxellized phantom

[Isabel Catarina Duarte]

Dear all,

I am trying to use NCAT phantom on CTscanner.
But during the simulation, this error consistently and continuously occurs:
 
Error: one of the matrix dimensions is zero!
ERROR - G4Box()::G4Box(): coiso_S
        Dimensions too small ! - 0, 0, 0

*** G4Exception : InvalidSetup
      issued by : G4Box::G4Box()
Invalid dimensions. Too small.
*** Fatal Exception *** core dump ***


Everyone knows what this means??
This is the .h33 file beginning :
