        title={skesa: eSKESA is a de-novo sequence read assembler for cultured single isolate genomes
    based on DeBruijn graphs. It uses conservative heuristics and is designed to
    create breaks at repeat regions in the genome. This leads to excellent sequence
    quality but not necessarily a large N50 statistic. It is a multi-threaded
    application that scales well with the number of processors. For different runs
    with the same inputs, including the order of reads, the order and orientation
    of contigs in the output is deterministic. },
