Fig. 2: Fusion detection by breakpoint clustering.

Violin plots overlaid with jitter plots show the distribution of chimeric/fusion read breakpoints for a set of samples selected for illustrative purposes. Chimeric breakpoints are expected to a have a relatively uniform distribution over the length of the amplicon, while true gene fusions should be concentrated within a narrow region. Fusions are called when a sufficient density of breakpoints is detected (see “Methods” and source code for full details).
