Patent ID: 7315785

Claim:
A program embedded in a computer readable medium for displaying a dendrogram comprising: a module for clustering a plurality of biopolymers with a first clustering method which is based on a set of gene expression data obtained by experiments on the plurality of biopolymers, and displaying clustering results thereof in a form of a dendrogram that is clustered based upon gene expression data of individual biopolymers in a display window; a module for selecting a subtree in the dendrogram in the display window; a module for displaying the selected subtree in the dendrogram in a separate display window thereby allowing a user to see in the separate display window more details of the selected subtree; a module for grouping biopolymers in the selected subtree in the separate display window into at least one function group sharing one of functional characteristics consisting of enzymatic, metabolic, transporting, and cell cycle functions; and a module for displaying said function group of biopolymers in the separate display window thereby confirming by the user that said function group in the selected subtree shares said one of functional characteristics consisting of enzymatic, metabolic, transporting, and cell cycle functions.
