Overview

The software package structure consists of several parts. The computational part of the program was written in C, and executables are distributed for various platforms (currently Windows, Linux, Sun). The C executable reads a data file supplied by the user. There is also a Java front end that provides various nifty plots and other helpful features for the user; however, you can also invoke structure from the command line instead of using the front end. This document includes information about how to format the data file, how to choose appropriate models, and how to interpret the results. It also has appendices on using the two interfaces (command line and front end).
