Hi,

you can specify which program you want to use to open eps file
in
input/mg5_configuration.txr

you can replace the line

#! Prefered PS viewer
#! If None: try to find one available on the system
# eps_viewer = None

by

#! Prefered PS viewer
#! If None: try to find one available on the system
eps_viewer = PATH_TO_EXECUTABLE

where you replace PATH_TO_EXECUTABLE to what fit your machine.

Cheers,

Olivier

Thanks,
by what fit my machine you mean I choose any folder to save diagrams?
Thanks again!

You have to pass the path to an executable which can open eps file.
(like gv, epsviewer,...)
You do not have any of standard one in your $PATH, so you have to tell us how to open such file on your machine

Cheers,

Olivier

Thanks again!

I have KDE okular . How can I determine its path?

Cheers,
Christina

Hi,

Sorry I do not know KDE okular (never even heard it before).
So I can not help you on that os.

Cheers,
