Identification of clustered insertion/deletion evidicnes.

<p>(a) The breakpoint pair of potential SV<sub>1</sub> is defined by the spanning region of the first discordant read <i>r</i><sub>1</sub>; (b) <i>r</i><sub>2</sub> and <i>r</i><sub>3</sub> are joined into <i>C</i><sub>1</sub> due to the overlapping with <i>B</i><sub>1</sub> in (a). <i>r</i><sub>4</sub> does not overlap with <i>B</i><sub>1</sub>; therefore, a new cluster <i>C</i><sub>2</sub> is created.</p>
