NOVEL METHOD FOR ANALYZING DATA COLLECTED BY MICROARRAY EXPERIMENT AND THE LIKE

摘要

A method for analyzing data comprising the steps of (1) determining a threshold on the basis of a data value such that the remainder of the subtraction of the background strength from the measured signal strength is negative and determining the range in which the quantitativeness of the logarithmic ratio between the signal value in a comparative experiment and that of the object experiment is assured by the threshold, (2) dividing the average strength into sections, calculating the average of the logarithmic ratios between the above-mentioned signal values in the sections, and correcting the deviation of when the logarithmic ratio is plotted with respect to the average strength, and (3) determining whether or not there is any correlation between the expression profiles of flanking genes determined by a microarray experiment or the like and predicting the transcription unit on a microorganism genome with high accuracy.
