Hi, I could not find this on the Web pages. I have a root file with several histograms. The number and the names of histograms varies from run to run. Is there a way to obtain the list of histograms (that I can see with ls()) and/or directorie names inside a macro? Thank you. Dr. Giovanni Organtini Dip.to di Fisica - Univ.
