Metrics of four bacterial assemblies by four assemblers.

<p>We show the corrected N50 lengths (y-axis) and accuracies (numbers on top of bars) of the four bacterial assemblies by four assemblers: (a) Velvet, (b) SOAPdenovo, (c) Newbler, and (d) CABOG. The accuracy of an assembly is defined as the ratio of the corrected N50 length to the N50 length before correcting assembly errors, and ranges from 0 to 100%. The four species are <i>C. marinum</i>, <i>E. coli</i>, <i>P. brasiliensis</i>, and <i>S. smaragdinae</i>. For each species, each assembler treats three types of data: original PE reads, recovered DNA fragments and the remaining PEs, and recovered DNA fragments and original PEs.
