Segmental duplication in the E. histolytica Rahman strain. High coverage across a region of scaffold DS571330 in the Rahman genome is confirmed by independently generated sequencing libraries (SOLiD and 454). The region encompasses seven genes and is flanked by repetitive elements. The black line represents coverage from Rahman SOLiD sequencing library, the dashed line represents coverage from Rahman 454 sequencing library, the grey line represents coverage from strain HM-1B SOLiD sequencing library, and is shown as a control. Coverage depth is displayed on a log scale in order to show both SOLiD and 454 data (where many fewer reads are generated) on the same plot.
