The present disclosure provides methods of processing or analyzing a sample. A method for processing a sample may comprise hybridizing a probe molecule to a target region of a nucleic acid molecule (e.g., a ribonucleic acid (RNA) molecule), barcoding the probe-nucleic acid molecule complex, and performing extension, denaturation, and amplification processes. A method for processing a sample may comprise hybridizing first and second probes to adjacent or non-adjacent target regions of a nucleic acid molecule (e.g., an RNA molecule), linking the first and second probes to provide a probe-linked nucleic acid molecule, and barcoding the probe-linked nucleic acid molecule. One or more processes of the methods described herein may be performed within a partition, such as a droplet or well. One or more processes of the methods described herein may be performed on a cell, such as a permeabilized cell.

The present disclosure provides instrumentation and automated methods for creating cell surface display libraries, where the cells of the library display engineered peptides on their cell surfaces for identification of antigens that bind to T-cell receptors. The engineered peptides may be putative antigens or binding regions of the T-cell receptors.
