Abstract:
A method for nucleic acid sequencing includes receiving a plurality of observed or measured signals indicative of a parameter observed or measured for a plurality of defined spaces; determining, for at least some of the defined spaces, whether the defined space comprises one or more sample nucleic acids; processing, for at least some of the defined spaces, the observed or measured signal to improve a quality of the observed or measured signal; generating, for at least some of the defined spaces, a set of candidate sequences of bases for the defined space using one or more metrics adapted to associate a score or penalty to the candidate sequences of bases; and selecting the candidate sequence leading to a highest score or a lowest penalty as corresponding to the correct sequence for the one or more sample nucleic acids in the defined space.
Abstract:
A method, computer program product, and system are provided to calibrate a sensor array with a plurality of sensors. The method can include sweeping a voltage of a reference electrode from a first voltage to a second voltage, where the reference electrode is in fluid communication with the sensor array. The output voltage of each of the plurality of sensors can be monitored at one or more voltages within the first and second voltages. An overall average gain of the plurality of sensors can be calculated at each of the one or more voltages. Further, an acquisition window for the sensor array can be determined. The acquisition window can include a maximum distribution of sensors that provides a maximal overall average gain at a particular reference electrode voltage.

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.
