Introduction to SNNS

SNNS is a very comprehensive package for the simulation of neural networks. It may look a little daunting for first time users. This section is intended as a quick starter for using SNNS. Refer to the other chapters of this manual for more detailed information.

Before using SNNS your environment should be changed to include the relevant directories. This is done by :

1. copy the file SNNSv4.1/default.cfg to your favorite directory

2. copy the file SNNSv4.1/help.hdoc to your favorite directory

3. Set the environment variable XGUILOADPATH to this directory with the command setenv XGUILOADPATH your_directory_path. You could add this line to your .login file, so that the help and configuration files are available whenever SNNS is started.
