1. A method for normalizing probe array intensity data, the method comprising: providing a computer with a computer program, wherein the program is designed to receive one or more data files, wherein each data file comprises a plurality of intensity values acquired from one or more probe arrays, and wherein the program is additionally designed to normalize intensity values stored in the data files; retrieving intensity values from one or more data files; normalizing retrieved intensity values, wherein the normalization is based upon a normalization subset of intensity values and interpolated intensity values, wherein the interpolated intensity values are based upon the normalization subset, wherein the normalization subset comprises one or more of the retrieved intensity values, and wherein the intensity values of the normalization subset are selected without analyzing every retrieved intensity value; and storing the normalized intensity values.
