WebGenome annotation is the process of identifying the coding and non-coding features in a set of genomic DNA sequences. Usually the sequences will come from a draft assembly in the form of contigs. The features are labelled and recorded in various file formats such as genbank or gff files. They can be displayed as tracks in genome browsers.
