Software for the Data-Driven Researcher of the Future Dr. Paul Fisher Paul.Fisher@manchester.ac.uk http://www.cs.man.ac.uk/~fisherp
What is myGrid? • An e-Science Collaboration Since 2001 • Numerous partners involved: • Manchester • Southampton • Oxford • EMBL-EBI • It provides sustainable and production quality software • Supported by OMII-UK, EPSRC and BBSRC • Mixture of developers, bioinformaticians and researchers Software | Services | Content | Skills | Community
Taverna myGrid Open Suite of Tools Client User Interfaces Workflow Repository Workflow GUI Workbench and 3rd party plug-ins Web Portals Service Catalogue Provenance Store Workflow Server Programming and APIs Activity and Service Plug-in Manager Open Provenance Model Secure Service Access, and Programming APIs
Huge amounts of data Microarray 1000+ Genes Next Gen Sequencing QTL regions 100+ Genes 10,000+ Genes How do I look at ALL the genes systematically?
Issues with current approaches • Scale of analysis task overwhelms researchers – lots of data • User bias and premature filtering of datasets – cherry picking • Hypothesis-Driven approach to data analysis • Constant changes in data - problems with re-analysis of data • Implicit methodologies (hyper-linking through web pages) • Error proliferation from any of the listed issues – notably human error • Solution Automate
Web Services • Technology and standard for exposing code and data resources by an means that can be consumed by a third party remotely • Describes how to interact with it, e.g. service parameters • Workflows • General technique for describing and executing a process • Describes what you want to do, including the services to use
What kind of Services? WSDL Web Services REST BioMart R-processor BioMoby SoapLab Grid Services Local Java services Beanshell Workflows
Who Provides the Services? • Open domain services and resources • Taverna accesses 3500+ services (11,874 operations) • Third party – we don’t own them – we didn’t build them • All the major providers • NCBI, DDBJ, EBI … • Enforce NO common data model. Can include your own services and resources too !!!
A public centralised and curated registry of Life Science Web Services ‘Web 2.0’-style website and API Allow anyone to register, discover and curate Web Services Community oriented with expert guidance Open content, open source, open platform www.BioCatalogue.org

Taverna and the ‘Cloud’ + Analysing Next Generation Sequencing Data
Analysing African Cattle with Taverna 2.2 • Different breeds of African Cattle • 10,000 years separation • African Livestock adaptations: • More productive • Increases disease resistance • Potential outcomes: • Food security • Understanding resistance • Understanding environmental • Understanding diversity • http://www.bbc.co.uk/news/10403254
The study • Lots of sites involved in Study: • Univeristy of Liverpool • University of Manchester • ILRI (Nairobi)…… • Genetic variation in cattle species • African breeds: N’dama, Boran and Sahiwal • Resistance to African trypanosomiasis infection (sleeping sickness) • Genetic differences to make one species more resistant? • Potential consequences of those genetic differences? • Pathways are affected by those changes?
The Analysis Problem • Sequenced DNA from 3 cattle breeds using SOLiD / Illumina • 22 million SNPs for Sahiwal alone • N’Dama, Boran ~ 11 millions SNPs each • Large data • Comparing new data with reference genomes • Identifying interesting differences • e.g. non-synonymous SNPs, stop lost, stop gained, splicing regions etc
MAP FILTER ANALYSIS The Analysis Pipeline (in Perl) Input SNP data from sequencer Map between Genome Builds (Liftover) Filter for SNPs in Exons SNP consequences Identifying damaging SNPs (Polyphen) Harry Noyes – University of Liverpool
Workflow and phases MSc Student - Mohammad Khodadadi Input SNP file Populate DB with start SNP’s and resource version numbers Lift-over: maps between UMD3 and BTA4 cow assemblies Exon positions from ENSMBL Find SNPs in Exon regions PolyPhen to mark “dangerous” SNP’s The result can be either a MySQL database or TSV / CSV download
What we will demonstrate • Uploading Next Generation Sequencing SNP data to the cloud • Creating a new experiment • Running a workflow on multiple cloud instances • Showing result output, including links to annotated SNPs
Loading inputs Experiment Metadata Input Provenance Jobs Status Input data summary
Summary of Workflow Output 11 Million SNP for N’ Dama Non-synonymous coding SNPs Polyphen predictions: probably damaging N.B. Number variances due to workflow and polyphen filtering process
Taverna • Taverna 2.2 execution engine • Large data processing • Pause, resume and cancelling workflows • Retry and parallelisation layer • Taverna 2.2 server • Remote workflow execution • Workflows launched from web pages • Workflows executed on the cloud Essential for cloud
Other New features Validation reporting • Loading and sharing service sets • Support for offline editing • New provenance features
