  • VectorBasehttp://www.vectorbase.orgBRC Meeting September 2011Upcoming challenges We expect to receive over 30 vector genomes in the next 1-2 years

    Further, our community is generating -omics transcriptome data for emerging genomes that need to be integrated

    To address these issues, we introduced prerelease sites

  • VectorBasehttp://www.vectorbase.orgIntegrating legacy (BRC#1) annotation dataEBI Projection from reference Aim:

    Gene prediction using high quality reference set from a related species.

    Overview When annotating a species for which we have a closely related reference species we can align the genomes and project from the high quality set onto the new assembly. This is more effective than a similarity build as it allows for building genes across contigs regardless of the assembly. Whole-genome alignment (WGA) between reference and target using BLASTz. Custom filter to ensure that each bp in the target genome is aligned to no more than one position in the reference genome. Project predictions through transformation of coordinates between reference and target assemblies.

    Summary Effective for low coverage and poor quality assemblies. Limited to reflect only orthologous loci between reference and target, i.e. no novel gene prediction. BRC Meeting September 2011

  • Examples of integrating data Still under active developmentCurrently > 15k samples from 1600 field collectionsUC-Davis data IR-base dataNeafsey et al. SNP-chip data

  • GMOD natdiv consortium:

  • GMOD Natural Diversity moduleLightweight schemaAll objects defined by ontologiesGeneralSO / GO / PATOSpp. specificIDOMAL / MIROFlexiblecan handle all data from consortiumVector spp. & butterfliesRice & peaches

  • TGMA Mosquito Anatomy Ontology; CARO/BFO TADS Tick Anatomy Ontology; CARO/BFO MIRO Ontology of Insecticide Resistance IDOMAL Malaria Ontology; extension: transmission VBCV Ontology/CV for completion of PopGen OPL (Parasite Lifecycle) with Priti Parykh, Chris Stoeckert et al. New IDO extensions: IDODEN (with S. Lonzano & R. Scheuerman) and IDOCHAOntologies hosted by VB

  • VectorBasehttp://www.vectorbase.orgGoal: Anopheles gambiae reference Many issues with the PEST assembly as a reference S molecular form is proposed as the next reference Sanger*Illumina454Hybrid assembly strategyMetrics of success

  • Still developing visualisations & curating dataBut have a dev site up already have imported all the UC Davis data & IR-baseAs well as neafsey data we saw in the genome browser. 15,000 samples *We entered into a collaboration with a diverse group of other sites including several other model organism DBs. and GMOD generic model organism database (extension of DB used in flybase)What we came up with*SMALL database under 25 tables. (ensembl core = 78 + variation = 38) (116 combined)Not species specific uses general ontologies and ones kitsos described. for new spp group, plug in new ontology

    Very flexible.

    On top of this weve built*(*) Sanger assembly is NHGRI funded one assembled by JCVI using data from JCVI/WashU() 150x coverage of Illumina from Broad Institute - Dan Neasey will update Wed 09:40

    normal metrics - N50 values and extended set of metrics from assemblathonCoverage statistics for EST/RNA-Seq and re-sequencing experiments
