Hi, VMC-users,
I started to create VMC-application on the base of example01. So, I
simply imported geometry from ROOT file (which was created by g2root)
as:
void NEMOTestMCApplication::ConstructGeometry()
{
TGeoManager::Import("mygeom.root");
gMC->SetRootGeometry();
}
Compilation is OK. But, run_g3.C scripts crashes with the message:
...
Geant3 has been created.
===> , created
### Geometry loaded from file...

It seems that geant3 don't see the geometry although it was created
successively. With run_g4.C the geometry is built (the only
question why number of node/volumes in TGeoManager (5/6) doesn't
correspond the number of phys/log volumes (4/5) in G4. But I suppose
that mother volume is not counted by G4 Is it so?):
Geant4 has been created.

Well, what could the origin of problem I'm wondering? Is some
addinional initialization or G4->G3 conversion required if geometry
imported from ROOT file?
I use ROOT 4.00/03

VMC-4 v 1.3
