The TCR is composed of \u03b1 and \u03b2 chains, encoded by the TRA and TRB genes, of which the variable regions determine antigen specificity. To generate novel biological insights into the complex functioning of immune cells, combined capture of variable regions and single-cell transcriptomes provides a compelling approach. Recent developments enable the enrichment of TRA and TRB variable regions from widely used technologies for 3\u2032-based single-cell RNA-sequencing (scRNA-seq). However, a comprehensive computational pipeline to process TCR-enriched data from 3\u2032 scRNA-seq is not available. Here, we present an analysis pipeline to process TCR variable regions enriched from 3\u2032 scRNA-seq cDNA. The tool reports TRA and TRB nucleotide and amino acid sequences linked to cell barcodes, enabling the reconstruction of T-cell clonotypes with associated transcriptomes. We demonstrate the software using peripheral blood mononuclear cells from a healthy donor and detect TCR sequences in a high proportion of single T cells. Detection of TCR sequences is low in non-T-cell populations, demonstrating specificity. Finally, we show that TCR clones are larger in CD8 Memory T cells than in other T-cell types, indicating an association between T-cell clonotypes and differentiation states.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Availability and implementation<\/jats:title>\n                    <jats:p>The Workflow for Association of T-cell receptors from 3\u2032 single-cell RNA-seq (WAT3R), including test data, is available on GitHub (https:\/\/github.com\/mainciburu\/WAT3R), Docker Hub (https:\/\/hub.docker.com\/r\/mainciburu\/wat3r) and a workflow on the Terra platform (https:\/\/app.terra.bio).
