[Gate-users] Material Gate

[Mohammad Hmodi]

Hello Gate-users

I use vGate. After writing the main.mac file,  it is executed in GATE
with the "Gate --qt mac/main.mac"

there is an error

((GateMaterialDatabase.cc (l.131): GateMaterialDatabase: could not
find the definition for material 'Copper' in material files))

 Then I copied the materials.xml  and GateMaterials.db files to the
simulation path but still the same problem

Please Help

Mohammad
