Cydney Nielsen (BC Cancer Agency Genome Sciences Centre, Vancouver, Canada)One challenge in large scale genome sequencing projects is reconstructing the full genome sequence from the short sub sequences produced by current technologies. Visualization can provide a valuable complement to automated computation in interpreting the output of an assembly program. We present ABySS Explorer, a sequence assembly visualization tool. ABySS Explorer employs a graph representation in which edges correspond to sequence contigs, and edge shape and color indicate sequence length and annotation, respectively. The resulting visualization elucidates the global structure of an assembly and reveals contig connections that are difficult to explore in any other tool. The interactive interface provides search functionality and retrieval of details on demand. We provide examples of its application to genome and transcriptome assemblies. While the current tool is designed for ABySS (Assembly By Short Sequences), our next generation sequence assembly algorithm, we will discuss its compatibility with other assembly outputs.
