Figure 4From: Improving draft assemblies by iterative mapping and assembly of short reads to eliminate gapsClosing gaps in de novo assembly comprising only Illumina reads. Schematic diagram showing the comparison of the original velvet assembly (3 contigs a, b and c) and the improved assembly in Salmonella enterica. The improved assembly was aligned to the reference sequence with 99.8% identity. The two closed gaps shown were 100% identical to the reference sequence. Contigs are indicated by grey bars; gene annotations are indicated by yellow boxes. Vertical lines highlight the gaps that are filled by IMAGE in the improved contigs. Below, a coverage plot showing the relatively even depth of coverage of realigned Illumina reads at the improved assembly, indicating no signature of misassembly.Back to article page
