Method of displaying gene data, and recording medium
View Patent ↗A method of displaying gene data assists in discovering expression patterns specific to gene functions and inferring the function of a gene of which the function is unknown. A threshold value representing the degree of similarity of expression patterns is established in advance, and genes having the same function and genes with similar expression patterns to them are extracted and displayed. Cluster analysis is performed on the extracted genes by re-selecting the experiment patterns for clustering. Calculations are performed to see how many functions the genes belonging to a subtree have, and the proportion of each function in the subtree is determined. If a proportion exceeds a predetermined threshold value, they are regarded as a cluster (collection of genes with similar functions) and extracted.
1. A method of displaying gene data, comprising steps of:
displaying a dendrogram obtained by performing cluster analysis on a plurality of gene expression patterns;
specifying a function of a gene to be cluster-extracted, and a condition for function cluster extraction; and
highlighting in the dendrogram a gene function cluster which satisfies the condition in units of subtrees in the dendrogram,
wherein the specified function is transport, glycolysis, or TCA cycle, and
the condition for extracting function clusters comprises a minimum ratio of a number of genes having the specified function within the subtree to a total number of genes within the subtree, and a minimum number of genes contained in one function cluster that has the specified function.
