# B Setting up

# B.1 Environments needed

The visualisation software is written using the Karma package (a library for networked data processing and visualisation). In order to be able to use this library, a number of environment variables have to be set. There are two ways of doing this:

1) is to type:

``source /usr/local/karma/.login``

You can also include this in your .login file.

2) if you are using the standard .login file, select Karma

# B.2 Operating Systems

All the programs here are available for Unix environments. I have ready access to the following platforms:

- sparc_SunOS
- sparc_Solaris
- i386_Linux
- mips2_IRIX6
- mips4_IRIX6
- alpha_OSF1

so I make binary distributions for these platforms. Karma has also been ported to the following platforms:

- rs6000_AIX
- mips1_ULTRIX
- hp9000_HPUX
- crayPVP_UNICOS
- c2_ConvexOS
- mips1_IRIX5
- mips2_IRIX5

but since I don't have ready access, binary distributions may not be forthcoming.

If you want to run Karma under another operating system, I will try to make the executables for it if I can get access to a machine.
