Hello, ROOT complains about non existing file. Could you check, that you run ROOT from the same directory where you run the example? The sequence of commands is: # go to the example build directory cd b4a_build # run the example ./exampleB4a -m run2.mac # check that the B4.root file exists ls *.root # start the Root session root.exe # call the Root macro to plot histograms root  .x plotHisto.C Could you try it out and let us know if the problem persists? Best regards,
