Genome Canada Bioinformatics Competition: Large-Scale Project
“A Federated Bioinformatics Platform for Public Health Microbial Genomics”
Our Goal
The IRIDA platform(Integrated Rapid Infectious Disease Analysis)
An open source, standards compliant, high quality genomic epidemiology analysis platform to support real-time (food-borne) disease outbreak
investigations

3
Each year, one in eight Canadians (or four million people)
get sick with a domestically acquired food-borne illness.
Partnership among public health agencies and academic institutes to bridge the gaps between advancements in genomic epidemiology and application to real-life and real-
time use cases in public health agencies
- Project Team has direct access to state of the art research in academia- Project Team is directly embedded in user organization
5
Interviews with key personnel to identify barriers to implement genomic epidemiology in
public health agencies
GAP 1: PUBLIC HEALTH PERSONNEL LACK TRAINING IN GENOMICS
Solution 1a: Build a User Friendly, high quality analysis platform to process genomics data
• Carefully designed and engineered software platform is just the starting point… User

Metadata Storage Application

Continuous Integration Documentation
• Easy to use interface hiding the technical details
Solution 1a: Build a User Friendly, high quality analysis platform to process genomics data
Solution 1a: Build a User Friendly, high quality analysis platform to process genomics data
Solution 1b: Build Portable and Transparent Pipelines
• Use Galaxy as workflow engine – large community support
• Retools to address usability, security, and other limitations
• Version Controlled Pipeline Templates• Input files, parameters, and workflow are
sent to IRIDA-specific Galaxy for execution• Results and provenance information are
copied from Galaxy
1. Input files sent to
Galaxy
3. Results downloaded from Galaxy

Solution 1c: Start the training NOW!
• Canada’s National Microbiology Laboratory has hosted genomic workshops for partners and collaborators
• IRIDA Project has dedicated funding for hosting workshops in 4Q of 2015 and 2016
• We would like to hear about other training initiatives and share experience and training material
GAP 2: INFORMATION SHARING IS INEFFICIENT AND AD-HOC
Many Players in surveillance and outbreak – ineffective information sharing

IRIDA is designed with these dilemma in mind
• Solutions:– 2a: Localized Instance of federated databases
– 2b: Permission Control – authentication /authorization for information sharing
– 2c: User role-based display of information
16
Solution 2a: Local/Cloud Instances and Data Federation
• Data processing capacity pushed to data generating labs• Allow data sharing securely for enhanced analysis• Eventually cultivating a culture of openness of data
sharing and collaborative development of tools
Authorization
Solution 2b: Security
• Local authorization per instance.• Method-level authorization.• Object-level authorization.• Allow secure, fine grained and
flexible information sharing
Solution 2c: Role-based Dynamic Display driven by Ontology
• Ontologies often lack a content management system (CMS)• An Interface Model Ontology (IFM) can define a CMS for an
ontology
IFM Interface View Permissions
Detailed View Restricted View
E.g. User role permissions control visibility and editing of content
GAP 3: INFORMATION REPRESENTATION IS INCONSISTENT
Solution 3a: Use Ontology
• Ontology: a way to describe types of entities and relations between them
• Why use ontology– Ontology is flexible and expandable– Lower levels of expressivity (e.g. controlled vocabulary,
data dictionary) are heavy handed and show low level of compliance and adoption
– Free text used as an alternative that are not computing friendly
– Ontology and semantic web technologies may be a solution
Many Domains of Knowledge are needed to describe an outbreak investigation Build On, Work With:
OBITypON NGSOnto NIAID-GSC-BRC core metadataMIxS Ontology NCBI Biosample etcTRANS – Pathogen Transmission EPOExposure OntologyInfectious Disease OntologyCARD, ARO for AMRUSDA Nutrient DBEFSA Comp. Food Consump. DB
Example gaps to be filled: Expand food ontology; expand CARD AMR data with others.
Lab Checklist/Ontology
• Currently finishing a lab/genomics checklist and starting an epidemiology checklist
• Metadata Domains:– Sample Collection– Sample Source– Environmental– Lab Analytics– Sequencing Process /QC– Sequencing Run /QC– Assembly Process / QC– Others overlapping with Epi: Demographic / Geographic / etc.
GAP 4: GENOMIC DATA INTERPRETATION IS COMPLEX AND TECHNOLOGY IS EVOLVING
Solution 4a: Use of QA/QC in IRIDA
• Software Engineering– High quality software that meets regulatory guidelines– Open Source product to ensure “white box” testing– Ontology driven software development– Follow proper software development cycle
• Data Quality– Built-in modules to check for input data quality – Warnings and Feedbacks during pipeline execution to laboratory technologists – Use of Ontology to check metadata (non-genomic) data quality
• Analytic Tool Quality– Utilize validation datasets– Use of abstract pipeline description – with version control– Periodic analysis of exceptions and boundary cases to assess tool accuracy
Solution 4b: Generation of validation datasets
