Before using Ferret, you must define its environment variables and execution paths. To do that execute the following command from the Unix shell prompt, or place the command in your .cshrc or .login file:
source /opt/local/ferret/ferret_paths
- On DEC OSF and Sun sunos computers:
- %
source /usr/local/ferret/ferret_paths
- Please NOTE: The source command should be placed before any
conditional exit you may have in your .cshrc or .login file.
This will prevent problems with the Ferret SPAWN command. Many initialization files around
PMEL contain conditional exit lines similar to these:
- # skip remaining setup if not an interactive shell
- if ($?USER == 0 || $?prompt == 0) exit
- # settings for interactive shells
If you are using a different computer, please ask a CNSD consultant to mount the disks on your system (the disks are /home/shiva, /home/shiva2, /home/shiva3, /home/shiva4, /home/shiva5). The data sets are located in the /data directories of these disks.
source /opt/local/ferret/ferret_shiva_paths
- On DEC OSF and Sun sunos computers:
- %
source /usr/local/ferret/ferret_shiva_paths
% ferret -gui
The beginners guided tour will get you started using the interface quickly. The basic steps are:
% ferret
TMAP's online documentation lists the available data sets; each is identified in a table under the heading 'Filename'. Open a data with the Ferret 'SET DATA' command. For example:
yes? SET DATA coads_since_1946
