Methods and apparatuses for estimating parameters in a predictive model for use in sequencing-by-synthesis
First Claim
1. A method of estimating a parameter related to sequencing of a sample nucleic acid template, comprising:
- (a) measuring signal data relating to nucleotide incorporation events resulting from a series of flows of nucleotides onto a sensor array comprising a plurality of regions of wells, at least one of the regions of wells comprising;
(i) a first set of wells including a first well containing the sample nucleic acid template and (ii) a second set of wells including a plurality of other sample-containing wells, wherein the first set of wells and the second set of wells are physically distinguishable from each other by shape or dimension;
(b) determining sequence information for the sample nucleic acid template using signal data from the first well containing the sample nucleic acid template;
(c) constructing a phase-state model for a set of nucleotide flows that contributed at least in part to the sequence information, wherein the model includes a signal correction parameter that is determined using signal data from the plurality of other sample-containing wells, and wherein the model is stored in a machine-readable memory;
(d) calculating, using the phase-state model, predicted signals for the plurality of other sample-containing wells resulting from the set of nucleotide flows;
(e) comparing the predicted signals to the signal data from the plurality of other sample-containing wells;
(f) fitting the signal correction parameter of the phase-state model based on the comparison of the predicted signals to the signal data from the plurality of other sample-containing wells; and
(g) storing the fitted signal correction parameter in the memory.

Abstract
A method of estimating a parameter related to sequencing of a sample nucleic acid template includes: receiving signal data relating to nucleotide incorporation events resulting from a series of flows of nucleotides onto an array of wells including (i) a first well containing the sample nucleic acid template and (ii) a plurality of other sample-containing wells; determining sequence information for the sample nucleic acid template using signal data from the first well; and constructing a phase-state model for a set of nucleotide flows that contributed at least in part to the sequence information, wherein the model includes a signal correction parameter that is determined using signal data from the plurality of other sample-containing wells.
