Root_exe.exe.stackdump

I use the following code to find the peak,but it only calculate to i=68, so I need to rerun from i=69.peaknumber(){ Int_t a,b,c; for (int i=1; i<=93; i++){ char fileName[128]; sprintf(fileName,"eventdata_rn%d.root",i); TFile *f=new TFile(fileName); c=h777->Draw("De1","Pur2<400"); a=h777->Draw("De1","Pur2<400&&De1>1000&&De1<3000"); b=h777->Draw("De1","Pur2<400&&De1>1500&&De1<2500"); cout<<i<<" "<<c<<" De1>1000&&De1<3000 "<<a<<" De1>>1000,1500,2500 "<<b; cout<<endl; //f->Close(); }}

My system is cywin, root_v5.17.04.win32gcc.tar.gz. Ther is a bug file:root_exe.exe.stackdump

Hi,

try:void peaknumber() { Int_t a,b,c; for (int i=1; i<=93; i++){ char fileName[128]; sprintf(fileName,"eventdata_rn%d.root",i); TFile *f=new TFile(fileName); TTree*tree = 0; f->GetObject("h777",tree); gROOT->cd(); // To make sure that the histograms are not deleted when the file is closed; c=tree->Draw("De1","Pur2<400"); a=tree->Draw("De1","Pur2<400&&De1>1000&&De1<3000"); b=tree->Draw("De1","Pur2<400&&De1>1500&&De1<2500"); cout<<i<<" "<<c<<" De1>1000&&De1<3000 "<<a<<" De1>>1000,1500,2500 "<<b; cout<<endl; delete f; } }

Cheers,
Philippe.
