Hello,
I am trying to use root to display a series of Histograms on a cent OS virtual machine.
I am supposed to call “root analysis.C” and this analysis.C file calls an output.root file that I think it may contain the data for the histograms.
After calling “root analysis.C” this appears:

I am trying to display the histograms for a Geant4 example called pdb4dna.
Thanks a lot for your help.
