Figure 2:

Diagram representation of a: a canonical V(D)J recombination event relative to the reference genome, b: partial (D-J only or V-D only) recombination event, c: non-canonical events involving multiple D genes, d: non-canonical events involving inverted V, D, or J sequences, and e: a rare non-canonical event involving two V-D recombinations. The “sequence read” shows the pattern we observed in the HiFi read while the above representation shows how is the read recombined from germline reference genome.
