Histograms with same name

[calbet]

Dear experts,
I have a root file with several different histograms with the same name (1), they differ with only a number at the end of the name (1). How can I specify a specific histogram? If I open this root file and get an histogram, which one it will take by default?
Regards

That number is the ‘cycle’ of the object.
Think of it as a revision.

If you don’t specify any cycle, the last one (the largest) will be automatically selected.

Search for “cycle” and/or “namecycle”, for example in: In a Nutshell: Input and Output . ROOT User’s Guide: Input/Output : Retrieving Objects from Disk , Subdirectories and Navigation . Just for reference: some additional notes about GetObject, Get, FindObjectAny, FindKeyAny, ReadObj, ReadObjAny .

Problem with Reading Root File

An expert’s advice is needed, why there is a “segmentation violation” in the code below. [8-[] { TFile *TPCTOFEfffile = TFile::Open("EFFTPCTOF.root", "read"); #if 1 /* 0 or 1 */ // This method works well. TH1F *TPCTOFEFFDeltapp = (TH1F*)(TPCTOFEfffile->FindObjectAny("hEff;1")); TH1F *TPCTOFEFFDeltamm = (TH1F*)(TPCTOFEfffile->FindObjectAny("hEff;2")); TH1F *TPCTOFEFFAverage = (TH1F*)(TPCTOFEfffile->FindObjectAny("hEff;3")); #else /* 0 or 1 */ // This method should also work, I get…
