  3. SED-ML Motivation BIOMD0000000139 , BIOMD0000000140 Simulation models Simulationresults (SBW Workbench)

  4. Example • First attempt to run the model, measuring the spiking rate v over time • load SBML into the simulation tool COPASI • use parametrisation as given in the SBML file • define output variables (v) • run the time course 1 ms (standard) 100ms 1000ms

  5. Example Second attempt to run the model, adjusting simulation step size and duration Fig.: COPASI simulation, duration: 140ms, step size: 0.14

  6. Example Third attempt to run the model, updating initial model parameters Fig.: COPASI, adjusted parameter values (a=0.02, b=0.2 c=-55, d=4)

  9. SED-ML Level 1 Version 1 UniformTimeCourseSimulation Figure: SED-ML structure (Waltemath et al., 2011)

  10. SED-ML Level 1 Version 1 • Carry out multiple time course simulations • Collect results from these simulations • Combine results from these simulations • Report / Graph the results

  11. SED-ML Level 1 Version 2 Simulation Model • UniformTimeCourseSimulation • oneStep • steadyState Task • Task • RepeatedTask Reports Data Generators

  12. SED-ML Level 1 Version 2 Parameter Scan Pulse Experiments Repeated Stochastic Traces Time Course Parameter Scan

  13. SED-ML next version • Focus on the integration of “data” with SED-ML, e.g., • experimental data for use in model fitting, parameter estimation • simulation data for testing implementations • Adoption of NuML as standard data description format • https://code.google.com/p/numl/ • XML description of underlying data (initially CSV). • provides a common data abstraction layer for SED-ML to utilise.
