[Gate-users] problem in NCAT phantom reading by GATE

[Saeed Heidary]

Dear all
I am using NCAT phantom , producing 10  frames and I have changed the
float32 format to uint16 , I am using the attenuation frames and using just
the average one of 10 frames  as a phantom in SPECT simulation in GATE.
I have made a table for attenuation coefficients and probably every things
ok !
but the problem !
Moreover I am utilizing benchSPECT ,example_TimeActivityCurve and
Voxelized_Phantom_Sourceby together to do my work.

I have compared my phantom and all *.atn frames in
example_TimeActivityCurve of GATE, they are fundamentally the same!
once using GATE phantom , there is no problem   but when I use my phantom
the error message is:


List of initialized processes:



[Core-0] Initialization of geometry
ERROR - G4Box()::G4Box(): cat1_solid
        Dimensions too small ! - 0, 0, 0

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

*** G4Exception: Aborting execution ***
Aborted


I would appreciate anybody can help me!
Many thanks
