TTree::LoadTree would return -2 and the entry should be entirely skipped.
@pcanal There is no “external event loop”. Just “t ->Draw(...)”, so the question is what will happen in this method.
@faca87 So, you now have several “suspicious” entries, which you need to inspect carefully (i.e., the main tree “t” and the corresponding entries in the friend “te” tree).
See ROOT: tree/treeplayer/src/TTreePlayer.cxx Source File line 2293
What should I do?
@pcanal So, from this piece of code, I assume such entries will automatically be “rejected” / “dumped”.
Actually, do you maybe know how to print “friend columns” here:
t->Scan("*", "..."); // prints only "t" columns but we also need the corresponding "te" columns
Actually, do you maybe know how to print “friend columns” here:
You have to explicitly name them (the wildcard implementation looks only in the main tree).
@faca87 So, you need something like this:
t->Scan("B1Scintparticles.ScintParticleID:B1ScintOutparticles.ScintOutParticleID:B1Scintparticles.ScintParticleKinEn:B1ScintOutparticles.ScintOutParticleKinEn:B1Scintparticles.ScintParticleTrackEvenID:B1ScintOutparticles.ScintOutParticleTrackEventID:B1Scintparticles.ScintParticleEventID:B1ScintOutparticles.ScintOutParticleEventID:B1Scintparticles.ScintParticleParentID:B1ScintOutparticles.ScintOutParticleParentID:B1Scintparticles.ScintParticleTrackID:B1ScintOutparticles.ScintOutParticleTrackID", "B1Scintparticles.ScintParticleKinEn - B1ScintOutparticles.ScintOutParticleKinEn < -0.5");
Actually. maybe this works better (entry numbers come from your previous “Scan” output):
std::cout << "\n"; t->GetEntry(58282); t->Show(); te->Show();
std::cout << "\n"; t->GetEntry(75258); t->Show(); te->Show();
std::cout << "\n"; t->GetEntry(129681); t->Show(); te->Show();
std::cout << "\n"; t->GetEntry(134897); t->Show(); te->Show();
std::cout << "\n"; t->GetEntry(142955); t->Show(); te->Show();
In particular, carefully inspect tree “expressions” that you use for the index:

I notice that most of them have a negative value of ScintOutParticleTrackEventID that is impossibile because in GEANT4 both the trackID and the eventID are defined using a counter starting from 0…
Try with:
te->BuildIndex("ScintParticleEventID", "ScintParticleTrackID * 1000 + ScintParticleParentID");
Unfortunately, as I wrote here
I get negative values also using
te->BuildIndex("ScintParticleEventID", "ScintParticleTrackID * 1000 + ScintParticleParentID");
Anyway, by this message:
I understand that branches should have integer values…
I simulated 6.2510^8 primary particles that is a number close to 2.110^9…so maybe the number of tracks is >2.1*10^9…could it be the reason of the problem?
Well, “6.25e8 < 2.1e9”, so using “ScintParticleEventID” as the “major” parameter should be fine.
Well, you will need to inspect these entries:
t->Scan("B1Scintparticles.ScintParticleID:B1ScintOutparticles.ScintOutParticleID:B1Scintparticles.ScintParticleKinEn:B1ScintOutparticles.ScintOutParticleKinEn:B1Scintparticles.ScintParticleEventID:B1ScintOutparticles.ScintOutParticleEventID:B1Scintparticles.ScintParticleParentID:B1ScintOutparticles.ScintOutParticleParentID:B1Scintparticles.ScintParticleTrackID:B1ScintOutparticles.ScintOutParticleTrackID", "B1Scintparticles.ScintParticleKinEn - B1ScintOutparticles.ScintOutParticleKinEn < -0.5");

So you seem to get exactly the same events with the new “index” as with the old one.
That means that you now need to inspect these entries and find out why Geant4 gave you such results.
BTW. In the new “Scan” string, instead of “B1Scintparticles.ScintParticleTrackEvenID:B1ScintOutparticles.ScintOutParticleTrackEventID”, I wanted to show “B1Scintparticles.ScintParticleEventID:B1ScintOutparticles.ScintOutParticleEventID”.
Sorry for the late reply …
then I will try to check what happen by Geant!
