I try now with LAS Armstrong to configure the ferret init script, but no success.
On the LAS web site it is explained (in an old page http://ferret.pmel.noaa.gov/FERRET_17sep07/LAS/FAQ/scripts_and_templates.html) that we must put ferret init script in a directory called server/jnl, but this does not exist.
How can I do that to customize my output plot ?
