Overlap finds overlaps between blunt contigs that have negative distance estimates. Add edges to the overlap graph.

ABySS is a de novo sequencing assembler developed for short reads of large genomes. It has novel scaffolding algorithm capable of assembling very large genomes including human genomes (>3.5 billion paired-end reads). ABySS algorithm eliminates ambiguities in the scaffold graph and identifies contigs that are assembled into scaffolds.The assembly runs in three stages: assemble contigs without paired-end information, align the paired-end reads to the initial assembly, and merge contigs joined by paired-end information.
