Hello,

The geometry is moved from the data files to the parameter file, this make the fRun->LoadGeomerty() method obsolete, and requires loading the parameters wherever the geometry is needed. usually this is the case for digi and reco macro.

please test it and let me know.

Mohammad

Hello,

I performed a simulation using "cbmroot/trunk/macro/run/run_sim.C" and tried to display geometry using correspondingly updated "eventDisplay.C" macro. The result is here:

In other tests I also can not find the geometry information. Which class is now responsible for the real writing this information to the parameter file? My "cbmroot/trunk" revision number is 6780

Hi,

you are missing the Trd library!


Quote:

-E- FairRootManager Branch: GeoTracks not found in Tree
-E- FairRootManager Branch: GeoTracks not found in Tree
FairMCPointDraw::Init() branch Monte-Carlo Tracks Not found! Task will be deactivated


in the run_sim.C macro the visualization flag is not set to true.



The geometry is now stored in the parameters (FairBaseParSet) exactly like the field. if you load the parameters the geometry will be loaded. if you would like to see the geometry in plain ROOT, then:



Quote:



//Load the libraries you need, then

TFile* file = new TFile("testparams.root");
file->Get("FairBaseParSet");

// now the geometry is available as TGeo in memory

gGeoManager->GetMasterVolume()->Draw("ogl");




regards

Mohammad

Hi. Mohammad,

Thanks for the hint with

file->Get("FairBaseParSet");



(I knew about libTrd Razz )

Regards,
Elena

Hi,

please run with gdb and send the output. I.e:

>gdb root.exe
root>.x much_hits_gem.C

regards

Mohammad
