Excavator is a computer software program for gene expression data clustering. It uses a set of unique clustering algorithms developed by the Computational Systems Biology Lab (CSBL) at the University of Georgia. Excavator represents data internally as a minimum spanning tree and outputs results to the user through the use of a micro-array data window, graphs, and a dendrogram viewer.

Features

• partitioning gene expressions profiles using multiple methods of clustering and definitions of distance between profiles.
• automatic selection of the most plausible number of clusters in a data set
• three different ways of viewing data: Micro-array, Gene Expression, and Dendrogram. As well as graphing individual genes from each cluster independently.
• identification of genes with expression profiles similar to specified seed genes
• cluster identification from a noisy background
• numerical comparison between different clustering results of the same data set
• runnable on UNIX/Linux/DOS command line as well as through a Java GUI
