Dear Root/Roofit experts,
I am playing with RooSuperCategory and I have some problems that I hope you’ll be able to solve.
I am trying to implement everything like if this was a simple category, but this is not working.
here is the relevant part of my script
[code]RooWorkspace* ws = (RooWorkspace*) file->Get(“wsp”);
RooRealVar* B_Mass = ws->var(“B_Mass”);
RooAbsPdf* pdf = ws->pdf(“pdf”);
RooDataSet* data = (RooDataSet*) ws->data(“data”);
RooCategory* cat = ws->cat(“fitCat”);
RooPlot* frameUp = B_Mass->frame();
data->plotOn(fplusUp, Cut(“B_ID==B_ID::Bplus && cosThetaSign==cosThetaSign::Up”) );
pdf->plotOn(fplusUp, Slice(*cat,"{Bplus;Up}"), ProjWData(*data)); // it breaks here
TCanvas* c = new TCanvas(“c”,“c”,20,20,800,600);
frameUp->Draw();[/code]
fitCat is my supercategory (from the workspace) and B_ID (Plus or Minus) and CosThetaSign (Up or Down) are the subcategories. Its states are reported here.
Table fitCat : data
±--------------±------+
| {Bplus;Up} | 13641 |
| {Bminus;Up} | 13208 |
| {Bplus;Down} | 13360 |
| {Bminus;Down} | 13359 |
±--------------±------+
It breaks when I plot the pdf and this is the stack trace:
[code] *** Break *** segmentation violation
===========================================================
There was a crash.
