[Gate-users] Define scanning geometry

[Stephen Yip]

Hi,

I am trying to create a sub-volume & insert material to it.

For example:


/gate/world/daughters/name cylindricalPET
/gate/world/daughters/insert cylinder
/gate/cylindricalPET/setMaterial Water


It complained that
/home/gate/Progs/gate_v6.2/source/geometry/src/GateMaterialDatabase.cc
.....GateMaterialDatabase: could not find the definition for material
'Water' in Material files....

It then kicked me out of vGate and closed OGLSX

Does anyone know what I did wrong?

Thanks,
Stephen
