SVDMAN is a program for singular value decomposition analysis of global gene expression data. It is designed to operate both as a stand-alone command line executable and as a component of larger systems for gene expression analysis. It is freely distributed by Los Alamos National Laboratory, please take a copy and use it or build it into your own system for gene expression analysis.
The methods are described in the following paper:
