A data access, model handling and data integration
platform for Systems Biology:
To support and manage the diversity of

Data, Models and experimental protocols from a
consortium
Web based
Standards compliant
Systems Biology of Microorganisms
http://www.sysmo.net


Pan European collaboration
13 individual projects, >100 institutes
 Different research outcomes
 A cross-section of microorganisms, incl.
bacteria, archaea and yeast

Record and describe the dynamic
molecular processes occurring in
microorganisms in a comprehensive way

Present these processes in the form of
computerized mathematical models

Pool research capacities and know-how

Already running since April 2007
Runs for 3-5 years
This year, 2 new projects join and 6 leave

Metabolic, gene network, kinetic
Relationships between data sets/experiments


genomics, transcriptomics
proteomics, metabolomics
fluxomics, reactomics
Procedures, experiments, data, results and models
Analysis of data
Challenges

Heterogeneous data and models
Distributed groups of researchers
Modellers and experimentalists have different
skills, training, experience
Scientists want to remain in control
Scientists reluctant to share

Rapid and incremental development
Driven by the PALs
Just enough and just in time , not Just in case
No reinvention
Sustainable and extensible
Migrate to standards
Fitting in with normal lab practices

Incentives for sharing




Safe haven for data
Credit and attribution
Help with exporting to public repositories (e.g.
One-click export to ArrayExpress, PRIDE etc)
A repository for “supplementary materials” in
publications


Linking publications and data
Access other resources through a SEEK gateway

How do we share
“Just Enough Results Model”

What type of data is it


What was measured


Microarray, growth curve, enzyme activity…
Gene expression, OD, metabolite concentration….
What do the values in the datasets mean

Units, time series, repeats….
Based on:

Minimum information models
e.g. MIAME, MIAPE, MIRIAM

Biological ontologies
e.g. Gene Ontology, MGED, SBO

Bioportal web service used in SysMO-SEEK for:
Concept lookup and visualisation
How do we share

Share JERM templates developed by SysMO-DB,
PALs and consortium



Spreadsheet templates
Database Schemas
Encourage uptake throughout SysMO



transcriptomics
metabolomics
proteomics etc….
RightField: Annotation by Stealth
Identifying Biological Objects

What do you have in your data?


Where/how do these objects interact?


Proteins/enzymes, genes/expression levels,
metabolites
Pathways, flux, experimental conditions
What models describe these interactions
Possible when using common frameworks,
naming schemes and controlled vocabularies
Following Standards

We recommend formats but we do not enforce
them






Protocols and SOPs – Nature Protocols
Data – JERM models and community minimum
information models
Models – SBML and related standards
Publications – PubMed and DOI
If you follow the prescribed formats, you get
more out, but if you don’t, you can still
participate
Lowering the adoption barrier
SEEK, the eLaboratory
A dynamic resource for analysis as well as browsing




Automatic comparison of data from inside files
Understanding where and how data and models
are linked
Running simulations with new experimental data
Running analyses and workflows over the data
and models
Workflows from myExperiment
Data preparation, annotation and analysis

Why it works for us



A solution that fits in with current practices
Start simple, show benefits, add more
Engage with the people actually doing the work

PhD students, Post-docs

Build to the PALs requirements
Respect publication cycles
Respect cultural differences

Scientists stay in control
