Editor's Notes
- #4: There is scope for a program that will link models, with experimental data that is perhaps in remote repositories, to the latest analytic tools, in a way that is straightforward for modellers to use.
- #6: Given a set of data, how to fit model parameters for it to reproduce that data?
- #7: Why are we tackling parameter estimation first? Predictive models are desirable e.g., for P4 medicine Search space dimensionality increases with each new parameter to fit Local minima are a big problem , therefore need global algorithms
- #8: This shows some of the projects in CSBE and how SBSI fits in. This central panel shows the standard way of making progress in Systems Biology â starting with a static model, experimental data is used to refine and generate kinetic models, which can inform new experiments This process can use various analytical tools; we envision SBSI as a sort of lubricating agent to facilitate this activity.
- #9: SBSINumerics â written in C++ for fast numerical algorithms SBSIVisual â client program for connecting with other projects, accessing SBSINumerics.
- #10: SBSINumerics â written in C++ for fast numerical algorithms SBSIVisual â client program for connecting with other projects, accessing SBSINumerics.
- #11: SBSINumerics â written in C++ for fast numerical algorithms SBSIVisual â client program for connecting with other projects, accessing SBSINumerics.
- #12: Outreach events for SBSI
- #13: Sought to increase interaction with databases and projects, both internal and external. 1) Databases âseek to ease incorporation of data & local models into modelling process
- #14: Sought to increase interaction with databases and projects, both internal and external. 1) Databases âseek to ease incorporation of data & local models into modelling process
- #15: SBSI is now installed on Hector
- #16: SED-ML - community standard - SBML very successful , now the accepted exchange format - but doesnât tell you what to do with the model - tedious manual process at present. - cmputational experiments will be be a greater proportion, models represent a huge investment of time effort and money -> need to maximise reuse.
- #17: Promote model re-use Currently is a manual process. Post processing of raw results may also be needed to emphasize the biological significance. SEDML automates this.

- #21: Jlibsedml in collaboration with Ion Moraru at University of Connecticut.
- #22: 3. SEDML support is built into SBSI, systems biology software weâre developing in Edinburgh. Next release ( due early May) will implement the level1 version 1 final spec. Example screenshot shows that one can export a simulation configuration to SED-ML using the SBSI software (www.sbsi.ed.ac.uk) Configure simulation Configure output including SEDML export Export to SEDML archive or file.
- #23: 1. Click on a SEDML file 2. Choose your output If the software can handle the modelling language and simulation type, it will produce the output. Screenshot shows the Elowitz repressilator example from the specification, reproducing the plots of normalized levels of protein.
- #24: This is under development â a graphical editor for SEDML. SEDML files can get quite complicated to look at once there are several models and tasks defined Aims are to allow easy viewing, editing and annotation, validating input, help with generating Xpath etc., and viewing models and their changes. Will be available as standalone app, Eclipse plugin, or SBSI plugin. Screenshot shows simple example and simulation configuration dialog.
- #25: Garuda â international collaborative project initiated and led by SBI Tokyo Aims to link software from different realms of systems biologyand ensure interoperability between applications.

- #31: Reuse and availability of existing code and resources
- #32: How can a fixed number of developers continue to maintain and develop new code.
- #33: Core modules are standard Java libraries and are resuable No cyclic dependencies.
- #35: Get other people to develop code Needs SDK but some interest from Bioclipse and Netherlands Cancer Centre
