MAKER Annotation Process Example of Glossina VectorBase Karyn Mégy Dan Hughes

VectorBase Hinxton Developer Meeting February 2012 Annotation: aims and means Aims –Preliminary –Locus rather than exact position Means –Automatic annotation By similarity Ab initio –Manual annotation By regions By gene families

VectorBase Hinxton Developer Meeting February 2012 Annotation: similarity vs. ab initio Similarity –Similarity to known sequences -> only know genes -> based on available data (qty, qlty) Ab initio –Follow a gene “recipe” -> potentially identify new genes -> over predictions
