Patent ID: 7359537

Claim:
A DNA microarray image analysis system which reads a DNA microarray image after hybridization and utilizes a feed forward neural network to analyze statuses of each spot of the DNA microarray image, wherein the DNA microarray is a Stanford type microarray having a plurality of blocked spot regions, the feed forward neural network includes a plurality of pixel value input units by the number of the plurality of pixels in one spot region and output units by the number of a plurality of statuses, and the output units correspond to the plurality of statuses which can be set in the one spot, region, the system comprising: a learning section for using as a teacher signal a status set in a spot region by a user, for inputting a plurality of pixel values in the spot region to the plural pixel value input units and for controlling the feed forward neural network to learn criteria to determine the statuses set in the spot region; and an automatic decision section for providing the plurality of pixel input units of the feed forward neural network after learning operation with a plurality of pixel values in a spot region designated by the user where statuses have not been set, to determine the statuses of the designated spot region.
