Dear Mohammad, Dear Florian,
thank you very much for your prompt help!
I got the macro running again using FairRun::CreateGeometryFile() and setting it up as Mohammad explained.
However, to make it finally work, I had to hack FairRunAna:
FairRunAna::SetGeomFile() does NOT instantly set the gGeoManager pointer, instead it sets the fInputGeoFile. This is then used in FairRunAna::Init() to load the actual TGeoManager into memory.
The problem with this approach is that Init() can only be called once,
if(fIsInitialized) {
fLogger->Fatal(MESSAGE_ORIGIN,"Error Init is already called before!");
exit(-1);
} else {
fIsInitialized=kTRUE;
}
...
Maybe I am overlooking some already present method to do this properly, but for now to make it work I hacked the setting of the gGeoManager pointer into the SetGeomFile() method of FairRunAna. I don't see a conceptual problem of doing that there, so maybe this should be changed ... what is your opinion?
Cheers and have a nice weekend!
Felix
