Appendix B: Installation Instructions

Installing the GUI is easy enough. Unpack the distributed archive using gunzip or winzip or any other client. Move into the jfeff folder.

On MS Windows, run `install win32.bat'. This will create a new file `jfeff.bat', which starts the GUI by double-clicking. If you're using precompiled binaries, you're good to go. You can copy the `jfeff.bat' file to your desktop or Start Menu for convenience. On Linux, run the script `install'. This will check system requirements and walk you through the necessary steps to start using jfeff. If you're using precombiled binaries, you're good to go.

The first time you open the GUI, you will have to tell it where the feff binaries are. Go into the Settings dialog and browse into the correct path. If you are using precompiled binaries, this should be something similar to `jfeff/feff90/win32' or `jfeff/feff90/unix', depending on your OS. If you are compiling the code yourself, we're betting your executables are in `jfeff/feff90/bin/Seq' or `jfeff/feff90/bin/MPI', unless you've tried to be smarter than us - in that case you're on your own.

Now you should be ready to open your first `feff.inp' file and start calculating. The Tutorial Chapter is an excellent place to start.

Note that the GUI will not work unless you have a recent version of Java. We believe that Sun Java SE JRE 5.0 or later should be good ; now is a good time to update. If you cannot install Java, you can still use the feff code from the command line.
