FSL requires a number of environment variables to be set properly. To achieve this source the config script from /etc/fsl/fsl.sh. One way to do this automatically is to add a line containing
to the .bashrc file in a users home directory (or a corresponding file for other shells than bash).
However, it is not necessary to manually source the configuration to use the GUI applications included in FSL.
FSL documentation and online help is provided by the fsl-doc package.
Questions regarding the usage of FSL or related theory can be posted on the FSL mailing list (see http://www.jiscmail.ac.uk/lists/fsl.html).
