PermutMatrix is a free software for gene expression microarray data analysis, published in Bioinformatics (2005), 21, 1280-1281.
It is a user-friendly work space designed to graphically perform data mining tasks like clustering and seriation analysis.
It relies on the graphical approach introduced by Eisen and would be useful for gene expression microarray data analysis.
It implements several seriation methods to find an optimal reorganization of rows and columns of a numerical dataset or leaves of a hierarchical clustering tree.
In many cases, optimal reordering methods could be very useful for microarray datasets analysis.
