Error with RooArgSet on ROOT 6.22/06

Roofit and RooStats
1

Hi I have a simple RooFit code which I usually run on ROOT 6.24/02 without any issues. I recently ran the same code on another computer using 6.22/06 and I got the error for RooArgSet:

error: no matching constructor for initialization of ‘RooArgSet’
…RooArgSet(RecCosThetaKK, RecCosTheta_BKK, RecDelRKK, RecDelR_BKK, RecPtKK, RecPt_BKK, RecMassKK, RecMass_BKK, RecMassLambdaKK, RecMassLambda_BKK, invMKK…

Here is the bit of code that concerns me:

 TChain* ch = new TChain("KsValidation");
  ch->Add("/people/apaul/Data/data1501.root");
 
  
  RooRealVar RecCosThetaKK("RecCosThetaKK", "RecCosThetaKK", 0.9998,1.);
  RooRealVar RecCosTheta_BKK("RecCosTheta_BKK", "RecCosTheta_BKK", 0.9998, 1.);
  RooRealVar RecDelRKK("RecDelRKK", "RecDelRKK", 3, 400);
  RooRealVar RecDelR_BKK("RecDelR_BKK", "RecDelR_BKK", 3, 400);
  RooRealVar RecPtKK("RecPtKK", "RecPtKK", 300, 2000);
  RooRealVar RecPt_BKK("RecPt_BKK", "RecPt_BKK", 300, 2000);
  RooRealVar RecMassKK("RecMassKK", "RecMassKK", 350, 650); //RecMassKK here
  RooRealVar RecMass_BKK("RecMass_BKK", "RecMass_BKK", 350, 650);
  RooRealVar RecMassLambdaKK("RecMassLambdaKK", "RecMassLambdaKK", 900, 5000);
  RooRealVar RecMassLambda_BKK("RecMassLambda_BKK", "RecMassLambda_BKK", 900, 5000);
  RooRealVar invMKK("invMKK", "invMKK", 3000, 7000);

  
  RooDataSet data("data", "data", RooArgSet(RecCosThetaKK, RecCosTheta_BKK, RecDelRKK, RecDelR_BKK, RecPtKK, RecPt_BKK, RecMassKK, RecMass_BKK, RecMassLambdaKK, RecMassLambda_BKK, invMKK), Import(*ch), Cut("RecCosThetaKK > 0.9999 && RecDelRKK > 4 &&  RecDelRKK < 300 && RecMassLambdaKK > 1125 && RecPtKK > 300 && RecPtKK < 2000 && RecCosTheta_BKK > 0.9999 && RecDelR_BKK > 4 &&  RecDelR_BKK < 300 && RecMassLambda_BKK > 1125 && RecPt_BKK > 300 && RecPt_BKK < 2000 && invMKK > 0 && RecMass_BKK > 478 && RecMassKK > 478 && RecMass_BKK < 518 && RecMassKK < 518"));

Could anyone help me to solve the issue?

Maybe @jonas or @moneta can take a look

Hi! Before ROOT 6.24, there was a limit on how many elements the RooArgSet constructor can take.

If you want your code to run also with older ROOT versions, you have to manually fill the RooArgSet in the case of many variables. I think the code would look like this:

RooArgSet variables;

for(auto& var : {RecCosThetaKK, RecCosTheta_BKK, RecDelRKK, RecDelR_BKK,
                 RecPtKK, RecPt_BKK, RecMassKK, RecMass_BKK,
                 RecMassLambdaKK, RecMassLambda_BKK, invMKK}) {
    variables.add(var);
}

RooDataSet data("data", "data", variables, ...et cetera...);

Hope that helps!

Hi @jonas, I did what you suggested. The error doesn’t show up now but root crashes. Here are the lines:

Not sure why it would crash. Thanks for the help!

Hi @jonas , I was wondering if I could still get some help with the crash. Sorry for any inconvenience but I couldn’t sort it out yet.
