摘要

Analysis data for each of the plurality of samples is acquired by the data acquisition section.A plurality of samples are classified into a plurality of basic groups by a classification section, and a tree of trees is formed by a phylogenetic tree preparation section based on the similarity of the pattern of drug resistance including the resistance to a plurality of specific drugs for a plurality of basic groups.Any of a plurality of nodes of the tree is designated as the attention node.A plurality of basic groups belonging to a plurality of child nodes for the attention node are reorganized into a plurality of reorganization groups corresponding to a plurality of child nodes by the reorganization section.By analyzing the difference of analysis data among multiple reorganization groups, a marker peak to determine the resistance to the drug corresponding to the attention node is searched by the analysis part.
