FERRET - An Analysis Tool for Gridded and Non-Gridded Data

Here, I just would like to provide some ideas in using FERRET.

The detailed information and userguide can be found in the web site : http://ferret.pmel.noaa.gov/Ferret/.

%Install FERRET on SUSE linux under bash environment:

Ferret can be installed as either a root or an user.

1. download the installation files (3 files) from http://ferret.pmel.noaa.gov/static/Downloads/ferret_downloads.html

• Ferret Executables (the file name could be fer_executables.tar.gz)
• Ferret Environment (fer_environment.tar.gz )
• Ferret Datasets (fer_dsets.tar.gz )

And, put in the directory (e.g. /tmp/)

2. Following the steps to install (an example for ferret v6.72):

1. create directory that you would like to put "Ferret Environment" in (e.g. /opt/ferret)
   • mkdir /opt/ferret
2. uncompress the environment file
   • cd /opt/ferret
   • zcat /tmp/fer_environment.tar.gz | tar xvf -
3. create directory that you would like to put "Ferret Datasets" in (e.g. /opt/ferret/fer_dsets)
   • mkdir /opt/ferret/fer_dsets
4. uncompress the datasets file
   • cd /opt/ferret/fer_dsets
   • zcat /tmp/fer_dsets.tar.gz | tar xvf -
5. install the executables
   • cd /opt/ferret/bin
   • ./Finstall
   • select 1 to install the excutables, modify the paths if need
   • select 2 to install the ferret_paths (usually put ferret_paths in /opt/ferret/)
   • select 3 to quit
6. modify ferret_paths (if need)
   • if you would like to use bash instead of csh, change the link of ferret_paths to ferret_paths.sh
     • rm -rf ferret_paths
     • ln -s ferret_paths.sh ferret_paths
   • comment out some parts that may cause some errors when you start Ferret, if need. (e.g. JAVA_HOME)
7. add the ferret_paths to your environment variables
   • add "source /opt/ferret/ferret_paths" to file ".bashrc" in your home directory.
8. re-login and try it.

3. Two links of Ferret tips are given as follows. The first one is the slide I used to teach in my group, the second one is shared by my colleague.
