# Cluster 3.0 for Windows, Mac OS X, Linux, Unix

Next: Contents

This is the manual for Cluster 3.0. Cluster was originally written by Michael Eisen while at Stanford University. We have modified the k-means clustering algorithm in Cluster, and extended the algorithm for Self-Organizing Maps to include two-dimensional rectangular grids. The Euclidean distance and the city-block distance were added as new distance measures between gene expression data. The proprietary Numerical Recipes routines, which were used in the original version of Cluster/TreeView, have been replaced by open source software.

Cluster 3.0 is available for Windows, Mac OS X, Linux, and Unix.
