Hello - I would like to save my generated data from
RooDataSet and RooDataHist in an output text or ROOT file.
For RooDataSet I see a simple way:
RooDataSet* tmodel_data=tmodel.generate(t,nevtot) ; tmodel_data->write(Form(“datagen/tmodeldata_%d.dat”,niter))
(a question: could above two lines be accomplished in a single call?)
But I could not figure out how to (in a few lines) save
RooDataHist* tmodel_hist=tmodel.generateBinned(t,nevtot) ;
as a ROOT TH1 histogram … Is there a function built in
RooDataHist that would enable that? (reading in TH1 and
converting it to RooDataHist is covered in manual, but the
opposite direction RooDataHist -> TH1 would also be useful …
Cheers, Emil
