Hi All
I am trying to look through eve, all the events in the run simultaneously rather than look at them one by one which the current gui lets me to do.
Is there a way for me to do it for example in the rutherford example in fairroot.
FairEventManager *fMan = new FairEventManager ();
FairMCTracks *Track = new FairMCTracks ("Monte-Carlo Tracks");
FairMCPointDraw *RutherfordPoints = new FairMCPointDraw ("FairRutherfordPoint",kBlue , kFullSquare);
fMan->AddTask(Track);
fMan->AddTask(RutherfordPoints);
fMan->Init();
this is the section of eventDisplay.C which lets me to look at stuff. should i put FairEventManager in some sort of event loop.
something like this:
// ----- Reconstruction run -------------------------------------------
FairRunAna *fRun= new FairRunAna();
std::string inFile = "data/test.mc.root";
TFile* f = new TFile(inFile.c_str());
TTree *t = (TTree *) f->Get("cbmsim");
fRun->SetInputFile(inFile);
fRun->SetOutputFile("data/test.root");
// ----- Parameter database --------------------------------------------
FairRuntimeDb* rtdb = fRun->GetRuntimeDb();
FairParRootFileIo* parIo1 = new FairParRootFileIo();
parIo1->open("data/params.root");
rtdb->setFirstInput(parIo1);
// ------------------------------------------------------------------------
FairEventManager *fMan = new FairEventManager ();
for (int i = 0; i<t->GetEntriesFast(); i++) {
t->GetEntry(i);
FairMCTracks *Track = new FairMCTracks ("Monte-Carlo Tracks");
FairMCPointDraw *RutherfordPoints = new FairMCPointDraw ("FairRutherfordPoint",kBlue , kFullSquare);
fMan->AddTask(Track);
fMan->AddTask(RutherfordPoints);
}
fMan->Init();
Thanks a lot
Raghav
