Dear experts,
I am quite new to the feature of TProof (in fact started to try my hands at it today only). So when I run few files by explicit addition of them in chain, the code works.
TProof *plite = TProof::Open("");
TChain *fChain = new TChain(“HGCalTBAnalyzer/HGCTB”);
fChain->Add(“root://eoscms.cern.ch//eos/cms//store/group/upgrade/HGCAL/simulation/2017/JulyTBv1/mc/CRAB_PrivateMC/crab_Ele100GeV/170820_214312/0000/TBGenSim_235.root”);
fChain->Add(“root://eoscms.cern.ch//eos/cms//store/group/upgrade/HGCAL/simulation/2017/JulyTBv1/mc/CRAB_PrivateMC/crab_Ele100GeV/170820_214312/0000/TBGenSim_200.root”);
fChain->SetProof();
fChain->Process(“SelectorCheck.C+”);
However when I try to read all the files from a directory changing this code as pointed out below, it give me an error :
Error in TDSet::Process: not a correctly initialized TDSet
And unfortunately I am not able to understand where this is coming from. Can anyone please help?
Thanks a lot and Best regards
Sandhya
