    Abstract: Methods for determining a location of a feature on a spatial array include (a) providing an array of features on a substrate, where a feature of the array includes a barcoded oligonucleotide having, in a 5′ to 3′ direction, a spatial barcode, a cleavage domain, and a constant sequence; (b) hybridizing a priming oligonucleotide to the constant sequence; (c) extending the priming oligonucleotide using the barcoded oligonucleotide as a template; and (d) determining all or a portion of a sequence of the extended priming oligonucleotide corresponding to the spatial barcode, or a complement thereof, and a location of the extended priming oligonucleotide, and using the location of the extended priming oligonucleotide to determine the location of the feature on the spatial array.
