This document is a more in depth description of the evidence based annotation technique used by the GEP. This document is designed to complement and extend the basic technique described in the Annotation for D. virilis PowerPoint.
This is a PowerPoint presentation describing the recommended strategies for annotating a D. virilis fosmid. The homology-based annotation strategy should also be applicable to annotation of D. erecta and D. mojavensis projects.
This PowerPoint presentation describes the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to NCBI BLAST, web databases, and the issue of reading frames and phase.
This decision tree illustrates the list of criteria that can be used to determine the putative D. melanogaster ortholog of a predicted gene.
This workflow provides an overview of the key analysis steps and bioinformatics tools for the annotation of a predicted gene in the Drosophila F element GEP project.
This document is the revised annotation report that GEP students will use to report their annotation results to the GEP.
This worksheet will guide you through a series of basic steps that have been found to work well for annotation of species closely related to Drosophila melanogaster. It provides a technique that can also be the foundation of annotation in other, more divergent species but in those cases other special techniques will probably be needed.
This walkthrough uses the annotation of a gene on the D. biarmipes Muller F element to illustrate the GEP comparative annotation strategy. This document shows how you can investigate a feature in an annotation project using FlyBase, the Gene Record Finder, and the gene prediction and RNA-Seq evidence tracks on the GEP UCSC Genome Browser. The walkthrough then shows how you can identify the coordinates of each coding exon using NCBI BLAST, and also includes a discussion on the phases of the donor and acceptor splice sites. The walkthrough concludes by verifying the proposed gene model using the Gene Model Checker; it also includes a sample GEP Annotation Report.
This PowerPoint presentation provides a brief primer on the recommended annotation strategy for Drosophila projects. The presentation provides an overview of the goals of the GEP annotation project, an introduction to RNA-Seq, web databases, and a discussion on the phases of the splice donor and acceptor sites.
This exercise continues your introduction to practical issues in comparative annotation. You will be annotating genomic sequence from the dot chromosome of Drosophila mojavensis using your knowledge of BLAST and some improved visualization tools. You will also consider how best to integrate information from high-throughput sequencing of expressed RNA.
