Hello all,

I was switching on the emStandard+optical process in the Geant4.
And then, I was accessing the file using a simple script below

TFile f("sim_emc.root","READ");

TTree *t=(TTree *) f.Get("cbmsim");

TClonesArray* track_array=new TClonesArray("TGeoTrack");
t->SetBranchAddress("GeoTracks",&track_array);

if (t) cout<<"here is t" <<endl;

cout<< t->GetEntriesFast()<<endl;
for(int i = 0; i < t->GetEntriesFast() ; i++)
{
cout << "Before " << i << endl;
t->GetEntry(i);
cout << "After " << i << endl;
}

And I got the Error below.
I do not get this error
when I do simulation with default hadron physics list.
I am not sure if it is already known problem, can anybody help me?

here is t

Hi,

I am not able to reproduce this problem, I run the sim_emc.C (adding the visualization flags) and changing the physics list to emStandard+optical. I am using the svn 8407.

regards

Mohammad

Hi,
Thank you for trying it.
I have missed a point here. I was fireing
photon of 200 MeV on electro-magnetic calorimeter.
I have included the boundary process by
having values of refractive index for both air and PWO.
I have included my media file which does that.
may be with this you must be able to reproduce the error.
Regards,
Vanni
