Hi,
I had one file. When it's in xrootd, TChain.GetEntries() just stuck. But when I copied it locally, TChain.GetEntries() works fine. Do you know what's the problem? The xrootd has no problem. I can easily copy the file with xrdcp from xrootd to local disk.
#root command
TChain chain("physics");
chain.Add("root://higgs15.cs.wisc.edu//atlas/xrootd/atlasdownloaddisk/skim/SlimYming/data11_7TeV.00191517.physics_Egamma.merge.NTUP_SMWZ.f413_m1025_p833_tid621784_00/NTUP_SMWZ.621784._000047.root.1");
Int_t nevent = chain.GetEntries();

Best Regards
Wen
