Modelling a metabolic pathway using Copasi When first faced with the task of modelling a biological system, the concept might seem a bit daunting.

A wide range of applications of the Virtual Cell are being developed as in-house research projects tutorila. A model for circadian oscillations in the Drosophila period protein PER. All concepts have been implemented in the user-friendly Matlab software ‘PottersWheel’, allowing modelers and experimentalists to study their systems and to obtain an optimal experimental design for a given research question.

The first part would comprise of a quick introduction to concepts in analog and digital circuitry e. The analysis encompasses structural analysis, tutoriall coefficients and the sensitivity of metabolites to small changes in individual parameters such as in enzyme concentrations or kinetic parameters.

Xopasi this data has been extracted from the literature which is cited at the bottom. Large network models are collected in KEGG database. Additionally, to date, more than 1, independent users worldwide have created and run simulations with the Virtual Cell. In practice one has to go back to the original literature in many cases.

In a close collaboration tutoriwl theoreticians and experimentalists we have developed an experimental design approach for the modeling of signal transduction pathways. From a long list of different organisms choose Homo sapiens. All enzyme concentrations are constant and similar That there is no decay of metabolites and that all reactions are irreversible and follow simple Michaelis-Menten kinetics.


Flux and concentration control coefficients tutorixl some of the outcomes of metabolic control analysis. Time course As one might imagine, this tool allows for plotting mostly anything as a function of time.

Engineering design principles for biologists Tutors: However, this tugorial is often disregarded with the motivation that the product in intermediate steps never reaches concentrations high enough to affect the flow of equilibrium with any significance. What products are produced?

Load the file into CellDesigner and answer OK for the conversion. These methods Laplace transformation, transfer function are implemented in the commercial software MatLab. It can be applied on model selection and parameter estimation tasks and considers tutprial constraints, like limited number of measurable players or data points, noise level and cell type specific experimentally realizable stimulations.

These methods have been embedded tuyorial our software CellNetAnalyzer successor of FluxAnalyzer; freely available for academic use via: Here you find the specific mechanisms of catalysis and regulation.

The workshop will start with an introduction to the software package presenting the main features of PottersWheel as well as key concepts of experimental design.


Additionally, one might want to consider what assumptions can be made and while still providing a functional model. The probably most common approach is the construction and analysis of dynamic models. It is supported worldwide by over software systems both open-source and commercial. Compare the slopes of the fluxes copssi the behavior of the flux control coefficients that you had computed for different values of the parameter.


Tuyorial broad acceptance of a common, open format for exchanging models between software tools is a crucial step towards wider use of quantitative modeling in biology, because it allows researchers to build upon each other’s work with greater ease and accuracy. CellDesigner is a graphically oriented model construction tool complementary to the text based reaction list for model editing in Copasi cf. Note that the variables are assigned accordingly in the menu below the function.

You can also gutorial values for the parameters. Skip to main navigation. In this tutorial, we present a number of partially new approaches and techniques aiming to a functional and qualitative analysis of the topology of cellular signaling and regulatory networks. Based on the new user-friendly Matlab parameter estimation and model selection framework PottersWheel A major challenge in Systems Biology is to evaluate the feasibility of a relevant biological research agenda prior to its realization.

The main Time Course screen. Follow a set of links signal transduction from a receptor looks like a yellow open book through the nucleus gene regulation to enzymes expressed from tutorjal of biochemical reactions converting metabolites green ovals. The participants shall evaluate vopasi different models, identify the correct one and estimate its parameter values based on quantitative experimental data as accurate as possible.
