CellDesigner is a process diagram editor for drawing gene-regulatory and biochemical networks. Intuitive user-interface helps to draw a diagram in rich graphical representation with our own design. Networks are drawn based on the process diagram, with graphical notation system proposed by Kitano.

CellDesigner is used for

• User-friendly visualization
• Modeling and simulation of genetic regulatory networks
• Protein networks and metabolic networks.

CellDesigner is SBML compliant software. SBML (System Biology Markup Language) is a standard computer-readable format for representing models of biochemical and gene-regulatory networks. SBML is applicable to metabolic networks, cell-signaling pathways, regulatory networks, and many others. Networks are able to link with simulation and other analysis packages through Systems Biology Workbench. CellDesigner uses SBML (System Biology Markup Language) to describe models and allow simulation of models using an integrated SBML ODE solver.

Cell Designer = SBML + Simulation + Databases Connections

In this tutorial we will learn about the basic components of the software, developing graphical model of a network, developing computational model & simulation of the model.

CellDesigner is a free and open software and can be downloaded from http://celldesigner.org

CellDesigner is implemented in Java, thus it runs on various platforms such as Windows, Linux, and MacOS X.

The current version of CellDesigner requires JRE (Java Runtime Environment). The installers for Windows & Linux include JRE 1.6, so no need to install Java before installing CellDesigner. On MacOS X, Java 1.6 is required.

The Spoken Tutorial Effort for CellDesigner is being contributed by Ms. Dasaka Kavita & Ms. Sakina Shaikh from IIT Bombay. Other contributors who helped in the creation of the scripts include Mr. Anil Patel & Ms. Reshma Patil from IIT Bombay who have contributed as 'Domain experts'.
