New search service Access from the EBI’s homepage Species selector allows for easy comparison • Data organised according to: • gene • expression • protein • structure • literature Explore data, return easily to your results
Goals of the new EBI Search • Relevant to ‘wet-lab’ biologists • Organises information based around a single gene (or a small number of genes) • User-expectation centric (not database centric) • Smooth transition to the detailed information in many of EBI’s core databases • NOT for bioinformaticians: does not provide programmatic access
Genomes 1: Ensembl Chromosomes Genes Genomic alignments Pick a genome Synteny Variations Variation Effect Predictor User Upload Gene trees Gene families
Genomes 2: Ensembl Genomes Genome portals for the five kingdoms of life Variation data for plant, metazoan and fungal species Interface uses Ensembl technology Multi-way comparison of whole bacterial chromosomes Pan-taxonomic comparative analysis
Nucleotides: European Nucleotide Archive (ENA) The ENA has a three-tiered data architecture. It consolidates information from EMBL-Bank, the European Trace Archive (containing raw data from electrophoresis-based sequencing machines) and the Sequence Read Archive (containing raw data from next-generation sequencing platforms). Figure adapted from: Cochrane, G. et al. Public Data Resources as the Foundation for a Worldwide Metagenomics Data Infrastructure.
