TFile initialization

ROOT
#1

Hi,
How can I modify the below code to make it work. Because when I run it, it gives me this error:

Error: can not call private or protected function main_likelihood95.C:31:
(compiled) 0 void TFile::operator=(const TFile&);
Calling : TFile::operator=(TFile);
Match rank: file line signature

  •    1 (compiled)   0 void TFile::operator=(const TFile&);

*** Interpreter error recovered ***

My code is :

TFile fq; if (lum=="100pb"){ TFile fq1("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L32.root"); fq = fq1; } else if (lum=="1fb"){ TFile fq2("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L33.root"); fq = fq2; } else { TFile fq3("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L34.root"); fq = fq3; }
Thanks.

Use

[code]TFile *fq = 0;
if (lum==“100pb”){
fq = TFile::Open("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L32.root");
}
else if (lum==“1fb”){
fq = TFile::Open("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L33.root");

}
else {
fq = TFile::Open("/data1/gumus/NewBinning/xsection/DijetHist_step7_newRecJet_L34.root");
} [/code]
