    Abstract: Provided herein are methods, systems, compositions, and kits that can determine spatial information between a plurality of analytes in a sample by tagging such analytes with tags, where identities and/or locations of such tags are previously unknown prior to tagging. Each of a plurality of analyte sequences may be tagged with multiple spatial tags, such that each analyte sequence is associated with a set of two or more spatial tags. The sets of spatial tags may be analyzed to generate a map of analyte sequences. The map may comprise information about the respective absolute positions of each of a set of sequences with respect to a reference sequence. The map may comprise information about the respective probability cloud (or likely location) of each of a set of sequences with respect to a reference sequence.

    Abstract: The present disclosure provides methods for nucleic acid sequence identification. The methods may comprise bringing a plurality of nucleic acid molecules in contact with a reaction mixture including a concentration of nucleotides that results in fractional labeling of the nucleic acid molecules. The methods may comprise starting a next reversibly-terminated, sequencing cycle prior to completion of unblocking of reversible terminators in a previous sequencing cycle.

    Abstract: Described herein are methods of generating a coupled sequencing read pair for a polynucleotide, and methods of analyzing the coupled sequencing read pair. The coupled sequencing read pair can be analyzed to detect polynucleotide variants, including at loci that are not directly sequenced within the coupled sequencing read pair. Other analytical methods can include using coupled sequencing read pairs to construct or validate a consensus sequence. The coupled sequencing read pair may be generated for a polynucleotide by generating sequencing data for a first region by extending a primer using labeled nucleotides; further extending the primer through a second region using nucleotides provided in a second region flow order, wherein primer extension through the second region is faster than primer extension through the first region; and generating sequencing data associated with a sequence of a third region of the polynucleotide by further extending the primer using labeled nucleotides.
