  • Verify that you can run a root session and display a histogram on your laptop.
    source /ds50/app/ds50/
    setup root v5_34_05 -q debug:e2
    root -l $DS50data/ds50/tutorial/test.cint
  • You should see a popup window that looks like the image below.
  • If no window appears, you may need to use ssh -X or ssh -Y.

  • To exit root, return the pointer focus to the window in which you ran root. Then type ".q" (without the quotes, with the leading dot) at the root prompt.
