You will need to provide the shortest working example of your script which causes the crash.

Dear ksmith:
Thanks for your reply. Here is the file that is causing the crash.

Best Regards

ksmith · January 26, 2018, 10:14pm

First step, remove all the unneeded headers that are cluttering your file (some class you included multiple times):

#include <TFile.h>
#include <TCanvas.h>
#include <TGaxis.h>
#include <TPad.h>
#include <TH1F.h>

//...

Secondly, this does not run as the input files are missing:

Error in <TFile::TFile>: file /afs/cern.ch/work/r/rkanwal/root_files/data_eta.root does not exist
Error in <TFile::TFile>: file /afs/cern.ch/work/r/rkanwal/root_files/mc_eta.root does not exist

If I instead create some fake data:

TH1F *h1 = new TH1F("h1", "H", 100, -2, 2);
TH1F *h2 = (TH1F*) h1->Clone("h2");
h1->FillRandom("gaus", 1E4);
h2->FillRandom("gaus", 1E4);

I get this result:

Also, the tabbing needed a little work.

Oh i m really sorry, i forgot to upload that input root files.
Here are the input files. mc_eta.root (10.2 KB)
data_eta.root (10.3 KB)

ksmith · January 26, 2018, 10:40pm

Your data files do not contain TH1F objects, but instead have TGraphAsymmErrors. You are forcing an incorrect cast and then have to suffer the consequences. Using a dynamic_cast will check if the type will work.

   TH1F *h1 = dynamic_cast<TH1F*>(f->Get("hxy_fit_eff;3"));
   TH1F *h2 = dynamic_cast<TH1F*>(f1->Get("hxy_fit_eff;3"));
   if (!h1 || !h2) {
      std::cerr << "ERROR: Unable to retrieve TH1F objects!\n";
      return;
   }

dpiparo · January 28, 2018, 7:59am

As @ksmith says or directly get from file an object with the correct type:

   TH1F *h1, *h2;
   f->GetObject("hxy_fit_eff;3", h1);
   f1->GetObject("hxy_fit_eff;3", h2);
   if (!h1 || !h2) {
      std::cerr << "ERROR: Unable to retrieve TH1F objects!\n";
      return;
   }

okay thank u so much dpiparo.
