Check to see if you already have Gnuplot, by typing 'which gnuplot' in a shell window. If Gnuplot is installed, you need to make sure that it is version 4.0 or newer ('gnuplot --version').
If you need to install Gnuplot, rpms are available from rpmfind.net and gzipped tar files from SourceForge. If you are using Debian Linux, Gnuplot will be downloaded and installed if you issue the following command as root: 'apt-get install gnuplot'.
Check to see if you already have Python, by typing 'which python' in a shell window.
If you have Python, type 'python'. The version number should be displayed. If this is less than 2.3, the scripts may not work with your currently installed Python version. (Press 'CTRL+D, ENTER' to exit.)
If you need to install Python, follow the appropriate instructions for your system at www.python.org. You should install the latest version of Python 2.3, or Python 2.4 (which also works fine with GaussSum). If you are using Debian Linux, Python will be downloaded and installed if you issue the following command as root: 'apt-get install python python-tk'.
Numeric is an extension to Python that allows efficient matrix manipulation. You should try to find a binary package for your system rather than compiling it yourself (check your package management system). An .rpm and source code is available from here. If you are using Debian Linux, Numeric will be downloaded and installed if you issue the following command as root: 'apt-get install python-numeric python-numeric-ext'.
The Python Imaging Library is a Python package that allows manipulation of images. GaussSum requires PIL to handle PNG images. You can get PIL 1.1.5 from here under "Python Imaging Library 1.1.5 Source Kit (all platforms)". This should be untarred into a folder in the usual way, using 'tar zxvf Imaging-1.1.5.tar.gz'. Next, go into the folder created and (as root) install the package as follows: 'python setup.py install'.
If you are using Debian Linux, the Python Imaging Library will be downloaded and installed if you issue the following command as root: 'apt-get install python-imaging'.
Download a gzipped tar of GaussSum here. This should be untarred into a folder in the usual way, using 'tar zxvf GaussSum-2.0.6.tar.gz'.
