To develop and evaluate ABySS, a parallelized de novo sequence assembler capable of efficiently processing massive short-read datasets from large-scale individual genome sequencing projects.
Designed a distributed parallel assembly algorithm (ABySS) capable of scaling across computing clusters to assemble short sequence reads.
Assembled a benchmark dataset of 3.5 billion paired-end reads derived from the publicly available genome of an African male.
Evaluated assembly performance via contig size metrics and validated novel non-reference sequences using alignments to alternative human and primate assemblies.
Generated approximately 2.76 million contigs ≥100 base pairs with an N50 length of 1,499 base pairs, representing 68% of the human reference genome.
Identified polymorphic and novel sequences absent from the human reference assembly that were confirmed through alignment against alternate human and non-human primate genomes.
