PermutMatrix: a graphical environment to arrange gene expression profiles in optimal linear order. PermutMatrix is a program to perform graphical analysis of a dataset. It implements several types of cluster analysis and a variety of methods for statistical seriation. Numerical values from the dataset are converted into a gradation of colours. Then rows and/or columns are permuted in such a way that a structure appears. A row or column ordering that reveals a statistical organisation in the dataset is searched. This approach has been widely used for many years in archaeology, sociology and operational research. It has new applications in biology, owing to Eisen’s work on the use of hierarchical clustering for gene expression data
