The Caenorhabditis brenneri genome was whole-genome shotgun sequenced to
a depth of 9.5X using plasmid and fosmid libraries made from DNA
extracted from a mixed population of females and males from all
developmental stages.  Coverage was calculated based on the assembled
genome size.  In addition, two rounds of primer-directed sequence
improvement were performed.  All the reads were assembled using PCAP
(Genome Res. 13(9):2164-70 2003). The assembly can be downloaded from
the GSC ftp site.

Funding for the sequence characterization of this genome was provided
by the National Human Genome Research Institute (NHGRI), National
Institutes of Health (NIH).
