    Abstract: Provided herein are methods of preparing a spatial array and methods for associating specific sample analytes with spatial locations in the spatial array. Provided herein are methods for preparing a spatial array using a plurality of primers attached to a substrate to guide a plurality of features to specific locations on the spatial array. In a non-limiting example, a plurality of primers on a substrate can be used to guide a plurality of first features that include capture probes onto the substrate. A plurality of second features that are configured to hybridize to the first features and also include capture probes are added to the substrate.

    Abstract: Disclosed are methods, compositions and kits for contacting a sample containing a biological particle with a catalyst associated with or attached to a support. The biological particle may be cells and/or nuclei. The catalyst may be an enzyme configured to digest an extracellular molecule, such as an extracellular biological molecule, including extracellular nucleic acid molecules. In some examples, the biological particle is an aggregate of cells that is processed to single cells with a nuclease that is attached to a bead support. The bead and nuclease may subsequently be removed from the system. The single cells that result from the method can be used in single cell-based droplet systems for obtaining genome or transcriptome profiles of single cells.

    Abstract: A method for aligning a sample to an array is provided. An image of sample image of a sample can be received by a data processor. The sample image having a first resolution. An array image including an overlay of an array with the sample and an array fiducial can be received by the data processor. The array image having a second resolution lower than the first resolution of the sample image. The sample image can be registered to the array image by aligning the sample image and the array image. An aligned image can be generated based on the registering. The aligned image can can include an overlay of the sample image with the array. The aligned image can be provided by the data processor. A method for detecting fiducials associated with an array is provided. Systems and non-transitory computer readable mediums performing the method are also provided.
