[kepler-users] Kepler -nogui execution without X11GraphicsEnvironment

[Matt Jones]

Did you try running the command line shell with the -nogui and -runwf
arguments? Something like:

kepler.sh -nogui -runkar /home/mbj/myworkflow.kar

The location of kepler.sh will vary by platform, but if you get it on your
path, then you should be good to go.  More details are here:
