Disclosed are methods for detecting spatial proximity relationships between nucleic acid sequences, such as genomic DNA, in a cell. The method includes providing a sample of one or more crosslinked cells comprising nucleic acids; permeabilizing isolated nuclei under conditions that preserve contacts; fragmenting the nucleic acids present in the nuclei; filling in and repairing the ends with at least one labeled nucleotide; joining the filled in end of the fragmented nucleic acids that are in close physical proximity to create one or more end joined nucleic acid fragments having a junction; isolating the one or more end joined nucleic acid fragments using the labeled nucleotide; and determining the sequence at the junction of the one or more end joined nucleic acid fragments.

Provided herein is a method for sample analysis. In some embodiments, the method may involve: (a) incubating a nucleic acid sample with a terminal transferase and a cyclooctene-functionalized nucleotide to produced cyclooctene-functionalized nucleic acid molecules; (b) tethering the cyclooctene-functionalized nucleic acid molecules to a tetrazine-functionalized support via an Alder cycloaddition reaction; (c) performing at least two separate primer extension reactions using the tethered nucleic acid molecules as a template to produce multiple distinct sets of primer extension products; (d) separately analyzing the sets of primer extension products using different methods to produce multiple data sets; and (e) integrating the data sets.
