    Abstract: Methods, systems, and apparatuses are provided for creating and using a machine-leaning model to call a base at a position of a nucleic acid based on intensity values measured during a production sequencing run. The model can be trained using training data from training sequencing runs performed earlier. The model is trained using intensity values and assumed sequences that are determined as the correct output. The training data can be filtered to improve accuracy. The training data can be selected in a specific manner to be representative of the type of organism to be sequenced. The model can be trained to use intensity signals from multiple cycles and from neighboring nucleic acids to improve accuracy in the base calls.

    Abstract: The invention provides methods and kits for ordering sequence information derived from one or more target polynucleotides. In one aspect, one or more tiers or levels of fragmentation and aliquoting are generated, after which sequence information is obtained from fragments in a final level or tier. Each fragment in such final tier is from a particular aliquot, which, in turn, is from a particular aliquot of a prior tier, and so on. For every fragment of an aliquot in the final tier, the aliquots from which it was derived at every prior tier is known, or can be discerned. Thus, identical sequences from overlapping fragments from different aliquots can be distinguished and grouped as being derived from the same or different fragments from prior tiers. When the fragments in the final tier are sequenced, overlapping sequence regions of fragments in different aliquots are used to register the fragments so that non-overlapping regions are ordered. In one aspect, this process is carried out in a hierarchical fashion until the one or more target polynucleotides are characterized, e.g. by their nucleic acid sequences, or by an ordering of sequence segments, or by an ordering of single nucleotide polymorphisms (SNPs), or the like.

    Abstract: The present invention is directed to methods and compositions for acquiring nucleotide sequence information of target sequences. In particular, the present invention provides methods and compositions for improving the efficiency of sequencing reactions by using fewer labels to distinguish between nucleotides and by detecting nucleotides at multiple detection positions in a target sequence.

    Abstract: The present invention provides methods of making and using self-assembled arrays of single polynucleotide molecules for carrying out a variety of large-scale genetic measurements, such as gene expression analysis, gene copy number assessment, and the like. Random arrays used in the invention are “self-assembled” in the sense that they are formed by deposition of polynucleotide molecules onto a surface where they become fixed at random locations. The polynucleotide molecules fixed on the surface are then identified by direct sequence determination of component nucleic acids, such as incorporated probe sequences, or by other decoding schemes. Such identification converts a random array of determinable polynucleotides, and their respective probes into an addressable array of probe sequences.
