Abstract

The present invention provides a system for analyzing an expression profile in which a large number of expression profile data obtained by a next-generation high-speed sequencer, a similar experimental technique, or the like is analyzed at high speed by a general-purpose computer, gene expression patterns are visualized, thereby easily analyzing to which gene a novel gene is similar in function. A system for analyzing an expression profile which analyzes gene expression profile data includes a storage unit which stores the number of counts of mRNAs expressed from a subject gene to be evaluated as expression data under each of a plurality of gene expression conditions for each subject gene name, a correspondence analysis unit which reads the expression data from the storage unit for each subject gene, and carries out correspondence analysis on the basis of the number of counts under each expression condition in expression data, a coordinate conversion unit which converts n-dimensional (n: natural number) scores obtained by the correspondence analysis to coordinate values for m-dimensionally (m: natural number, m≦n) arranging each subject gene, and an image processing unit which carries out plotting along the corresponding coordinate values for each gene to display the result on an image display unit.
