I am trying to reconstruct two Z bosons. I am using this tutorial as an example. https://root.cern.ch/doc/master/df103__NanoAODHiggsAnalysis_8C.html However, I am still not familiar in using ROOT data frame and I am writing it in terms of what I am familiar with. What I do not understand is how c…

Hi, Charge is declared as a float but you are using it as if it was an array, that’s what the compilation error is about. Hope this helps, Enrico

Thank you. That makes sense! I just don’t understand now why I get this error: In file included from input_line_205:1: /mnt/c/1/MG5_aMC_v2_6_6/Delphes/examples/selectMuon.C:82:33: error: use of undeclared identifier ‘PT’ auto idx_cmb = Combinations(PT, 2); ^ /mnt/c/1/MG5_aMC_v2_6_6/Delphes/ex…

[TBrowser] Here is how my Delphes;1 Tree looks

Thank you for sending the documentation. I may have found something useful. In my above code, I am trying to define the branches PT, Eta, Phi, and Charge. (I don’ have a Mass Branch though). I first attempt to extract the branches from my tree (called Delphes that is under the .root file created by…

probably need to use strings as parameter rather than undefined variable names.

@pcanal Do you have an example of how I can use branches as strings? Thank you
