Hi Rene, thanks for the answers. Yes I wrote my mail very fast, sorry for the confusion! I reformulate the remaining open questions. .root_hist: OK to change the name, but how can I tell root to keep more than the last 100 commands? I checked that this is not written in the User's Guide. not expanding cuts: I give an example to be more clear. In an interactive session, I want to analyze a root tree and try all sorts of cuts. I first define a lot of simple cuts, then more and more complicated cuts by combining the simpler ones, e.g.: TCut eta_e("abs(Etaele) < 2"); TCut pt_e("pTele > 20"); TCut eta_jet1("abs(Etajet[0] <2"); TCut pt_jet1("pTjet[0] > 20"); TCut eta_jet2("abs(Etajet[1] <3"); TCut pt_jet2("pTjet[1] > 10"); TCut ele(pt_e && eta_e); TCut jets(eta_jet1 && pt_jet1 && eta_jet2 && pt_jet2); TCut presel(ele && jets); and so on... Then, when I draw a plot, e.g.: MyTree->Draw("pTjet[2]",presel && "nbjets > 2"); root automatically expands the cut definition in the title box, which makes it unreadable except for very simple cuts. Now I can ask my question again: how can I tell root to keep original cut names and NOT to expand cut definition, i.e. in my example how can I end up with only ` presel && "nbjets > 2" ' in the title box of my plot? I checked it is not written in the User's Guide, at least not in the TCut section of Trees chapter. I hope my question is clear now. Thanks for help. -- Bets regards, Bernard Andrieu ----------------------------------------------------------------------- ("-/")_.-'"-._ LPNHE, 4 pl.
