[Manual annotation of the pig whole genomic sequence using Otterlace software].

In November 2009, scientists from the US, UK, and other countries announced the complete genome sequence draft of the domestic pig. With the release of improved versions of the pig genome assembly and the increase of correctly assembled sequenced fragments over the past two years, it is particularly urgent to have the pig genes annotated at whole-genome level. This article is aimed at introducing an excellent manual annotation tool, Otterlace software, developed by Sanger institute.
