Ensembl Fruitfly What's New v21.3a.1 (10 May 2004)

	Ensembl: Latest Developments
	v21.3a.1 Update Ensembl fruitfly v21.3a.1 is a minor update, made to accompany the chimp release, and updated genebuilds for human and Fugu. The new/updated fruitfly data in release 21 are:   Compara database - New BLAT alignments - Homologues extended to include mammals vs Diptera/Nematoda The canonical data for Drosophila is managed at FlyBase and we are working in partnership with them to provide feedback on their resources. Schema changes in v21    Compara database - New sequence table, and the addition of a sequence_id in member (and removal of member.sequence). - New version column for peptide/gene versions in the member table. - New genebuild column in the genome_db table, to allow for different gene builds off the same assembly. New features in v21    ContigView   Haplotype and Pseudo Autosomal Regions (PAR) are now displayed on ContigView. The chromosome-level display indicates the long-range position of these assembly features, while the detailed view colours these regions differently (red for Haps, blue for PARs). Clicking on the HAP/PAR track allows you to switch between the different versions of the assembly.   FirstEF track added. This track shows features produced by FirstEF: a first-exon and promoter prediction program for human DNA (http://rulai.cshl.org/tools/FirstEF)    GeneView   Displays alternative location for genes (e.g. in a PAR/HAP)   New GeneDAS sources - HUGO_text : an experimental source of Medline text-mining for HUGO symbols - GAD: the Genetic Association Database tracks papers reporting association studies to around 2,000 disease genes.
