[gate-users] missing materials

[Nehmeh, Sadek/Medical Physics]

One fix can be what Jose suggested, that is using geant4.7.0 instead.

Hi all,

I found the same erros after I install Gate 2.2.0 with GEANT4 7.1.
GateMaterials.db did in the gate directory. If I remove GateMaterials.db
and run Gate again, it shows another error of that GateMaterials.db can
not find.
It means that the program does find GateMaterials.db.

With GateMaterials.db in the gate directory, the details of the erro
message are below:

---> warning from G4Material::GetMaterial(). The material: Air
does not exist in the table. Return NULL pointer.

---> warning from G4Element::GetElement(). The element: Nitrogen 
does not exist in the table. Return NULL pointer.

---> warning from G4Element::GetElement(). The element: Oxygen 
does not exist in the table. Return NULL pointer.

---> warning from G4Element::GetElement(). The element: Argon does 
not exist in the table. Return NULL pointer.

---> warning from G4Element::GetElement(). The element: Carbon 
does not exist in the table. Return NULL pointer.

It seams to me that error is in the calling of 
G4Element::GetElement().
Could you tell me how to fix it?

Thanks


Yuxin
