Methods, systems, and computer-readable media for processing spatially related sequence data received from a sequencing device are presented. In one or more embodiments, a computing platform may receive, from a sequencing device, image data associated with a sample. The computing platform may identify, based on the image data received from the sequencing device, a first sequence located at first spatial coordinates. Subsequently, the computing platform may store, in a spatially searchable database, a first data element comprising the first spatial coordinates and a first identifier corresponding to the first sequence to spatially relate the first sequence to other sequences present in the sample. In some instances, the image data received from the sequencing device may include spatial information, temporal information, and color information associated with the sample, and the computing platform may present, on a display device, information identifying a presence of the first sequence at the first spatial coordinates.

Systems and methods for spatial analysis of analytes are provided. A data structure is obtained comprising an image, as an array of pixel values, of a sample on a substrate having a identifier, fiducial markers and a set of capture spots. The pixel values are used to identify derived fiducial spots. The substrate identifier identifies a template having reference positions for reference fiducial spots and a corresponding coordinate system. The derived fiducial spots are aligned with the reference fiducial spots using an alignment algorithm to obtain a transformation between the derived and reference fiducial spots. The transformation and the template corresponding coordinate system are used to register the image to the set of capture spots. The registered image is then analyzed in conjunction with spatial analyte data associated with each capture spot, thereby performing spatial analysis of analytes.

A method of modeling a background signal when sequencing a polynucleotide strand using sequencing-by-synthesis includes: flowing a series of nucleotide flows onto a reactor array having multiple reaction confinement regions, one or more copies of the polynucleotide strand being located in a loaded reaction confinement region of the reactor array, the loaded reaction confinement region being located in a vicinity of one or more neighboring reaction confinement regions that may or may not be loaded; receiving output signals from the reactor array; and modeling a background signal for the loaded reaction confinement region using the received output signals and a model adapted to account at least for an exchange of ions between the one or more neighboring reaction confinement regions and a headspace adjacent the loaded reaction confinement region and the one or more neighboring reaction confinement regions.
