Abstract:
1. A program storage device readable by a machine, embodying a program of instructions executable by the machine to perform method steps for calibration of polynucleotide sequence data, said method steps comprising: (i) receiving a set of fluorescent emission intensity signals where each of said fluorescent emission intensity signals of said set is comprised of a plurality of component signals, with each of said component signals representing a respective nucleotide base or an internal standard in a multicomponent mixture including a plurality of analyte polynucleotide fragments of unknown nucleotide sequence; (ii) determining a first component signal corresponding to the internal standard; (iii) determining a second, third, fourth and fifth component signal representing the respective nucleotide bases; (iv) identifying features from said first component signal and determining at least one peak-shape characteristic thereof, (v) generating a calibration model based at least in part on said at least one characteristic, and applying said calibration model to said second, third, fourth and fifth component signals, and (vi) reporting the result of applying said calibration model to said second, third, forth and fifth component signals to a user.
