[Gate-users] How to open GATE output files

[surabhi balagopal nair]

Thank you very much David and Santos.

I was using vGATE and when I tried the mentioned steps in the terminal of
the virtual box, the program said there was some segmentation error.
However, when I tried the same steps on my desktop, it worked marvelously
well!

Thank you again,
Have a wonderful day :)
