Dear all,
First I wish you to all a very Happy New Year 2012!
I am migrating some ROOT macro to pyRoot and is quite easy except for RooDataSet where it failed to convert some of the argument !!
For example :
but
[code] .py : tZZ = RootFile_tZZ.Get(“tree”)
weight = ROOT.RooRealVar(“weight”,“weight”,0,100000)
mass = ROOT.RooRealVar(“mass”,“mass”,MassMin,MassMax)
var = ROOT.RooArgSet(mass,weight);
d = ROOT.RooDataSet(“d”," zz mass spectrum ",var,ROOT.RooFit.Import(tZZ),0,“weight”) [/code]
doesn’t work :
[quote] d = ROOT.RooDataSet(“d”," zz mass spectrum ",var,ROOT.RooFit.Import(tZZ),0,“weight”)
TypeError: none of the 8 overloaded methods succeeded. Full details:
RooDataSet::RooDataSet() =>

RooDataSet::RooDataSet(const char* name, const char* title, const RooArgSet& vars, const char* wgtVarName = 0) =>

RooDataSet::RooDataSet(const char* name, const char* title, TTree* t, const RooArgSet& vars, const RooFormulaVar& cutVar, const char* wgtVarName = 0) =>

could not resolve RooDataSet::RooDataSet(RooDataSet const&,const char*)[/quote]
while :
works fine!
this is a naive question but how can I add the missing agruments in the function “RooDataSet” ? How can I easily see the expected argument for the python "fonction " ? For example for RooDataSet it seems that the argument var and TTree are in the opposite order than the C function !
Thanks a lot
Cheers
