Hello Everyone,

I need your help.

I have installed trunk CBM root.I am trying to plot invariant mass spectra of dimuons. for that I have taken jpsi.root as input signal and urqmd.auau.10gev.centr.root as background input to much_sim.C macro and I ran much_seg_sector.C macro.Then I was trying run much_reco.C macro in cbm root trunk.then I got the reconstruction root file which contains the branches like global trcks, much tracks, primary vertex etc.

My problem is that when I try to open the primary vertex branch, it gives me following error


Error in <TTreeFormula::Compile>: Bad numerical expression : "PrimaryVertex.PrimaryVertex.fX"
Info in <TSelectorDraw::AbortProcess>: Variable compilation failed: {PrimaryVertex.PrimaryVertex.fX,}
Error in <TTreeFormula::Compile>: Bad numerical expression : "PrimaryVertex.PrimaryVertex.fY"

Error in <TTreeFormula::Compile>: Bad numerical expression : "PrimaryVertex.PrimaryVertex.fNTracks"
Info in <TSelectorDraw::AbortProcess>: Variable compilation failed: {PrimaryVertex.PrimaryVertex.fNTracks,}


Actually I have seen that the co-ordinates of primary vertices were being printed as output but I think it not filled in tree.


Can anyone help me regarding this?
