Determining relative expression for probe groups in probe arrays

摘要

A method of determining relative expression for probe groups in probe arrays includes: determining probe values for one or more probe arrays of a baseline category and multiple probe arrays of an experimental category, where each probe array includes a plurality of probes organized by probe locations; determining, from the probe values corresponding to the probe locations, probe categories for the probe locations, where each probe category corresponds to the baseline category, the experimental category or an indefinite category; and determining, from the probe values and the probe categories, a category bias for a probe group, where the probe group includes multiple probe locations, and the category bias including a preference for the baseline category, the experimental category or the indefinite category.
