Re: How to load up a TTree in a RooDataSet inside PyRoot???

Augusto,

> I followed the suggestion and this are the error messages:

yes, but that's no longer related to the Import(tree). If you read the error message, it says that none of the methods takes a RooArgSet as a third argument.

>From the looks of it, in this:

> 85 rooData= ROOT.RooDataSet('data', 'dataset'
> , ROOT.RooArgSet(rooVar)
> ---> 86 , ROOT.RooFit.Import(tree) ,
> ROOT.RooFit.Cut(Cut + ' && 1' ))

the third and fourth arguments are inverted, for the match with:

> RooDataSet::RooDataSet(const char* name, const char* title,
> RooDataSet* data, const RooArgSet& vars, const RooFormulaVar&
> cutVar, const char* wgtVarName = 0) =>
> could not convert argument 3

Best regards,
