Abstract

The present disclosure provides methods and systems for generating and using indices in a synthetic three-dimensional (3D) matrix within a biological sample (e.g., a cell or a tissue sample). The present disclosure provides a method for processing or analyzing a nucleic acid molecule having a three-dimensional (3D) spatial position in a cell or cell derivative can comprise: (a) using a transposase to insert a nucleic acid index sequence into the nucleic acid molecule to generate an indexed nucleic acid molecule comprising the nucleic acid index sequence; (b) detecting the nucleic acid index sequence of the indexed nucleic acid molecule to identify the 3D spatial position; (c) subsequent to (b), removing the indexed nucleic acid molecule or derivative thereof from the 3D spatial position; and (d) identifying a sequence of the indexed nucleic acid molecule or derivative thereof removed from the 3D spatial position in (c).
