A Framework for Annotating High-Throughput Genome-Wide Screens Josh Mooreintelligent Bioinformatics Systems (iBioS)
Outline • Problem • Framework • Tool-Issues
Outline • Problem : MitoCheck • Framework • Tool-Issues
Problem • MitoCheck (EU FP6) • 5D images from genome-wide screens (RNAi) • Multiple images for each human gene • 10-100 TB of data over the next 4 years • Goal: Automated classification of phenotype
Outline • Problem • Framework : Open Microscopy Environment • Tool-Issues
Framework “OME defines a set of information common to all biological microscopy, a format for storing this information, and a mechanism for sharing it with other software” • HTTP interface • LSID capable • XML exchange format BasicArchitecture
Outline • Problem • Framework • Tool-Issues : Annotations anyone?
a:Annotation dc:created a:context dc:modified dc:creator a:annotates rdf:type a:body @prefix a: http://www.w3.org/2000/10/annotation-ns# Tool-Issues • Provide RDF layer • Useful for exporting metadata • Suggestion: Annotea • Solves “N-ary” problem • Existing tools • But “only” Live Early Adoption and Demonstration (LEAD) project
Tool-Issues • Hypothetical Query: select ?gene where (?annotation1, a:annotates, ?image) (?annotation1, rdf:type, ex:Phenotype) (?annotation1, a:body, ex:somePhenotype) (?annotation2, a:annotates, ?image) (?annotation2, rdf:type, ex:KnockedOutGene) (?annotation2, a:body, ?gene); • Result Bindings:[?gene ex:gene00001][?gene ex:gene19404]...

Tool-Issues • Open: • If not Annotea, what? • Confidence/Trust • Retraction/Negation • Rules • LSIDs in Mozilla
