SBW is a lightweight framework that allows different applications written in different languages and on different platforms to communicate. BioSPICE/SBW – Systems Biology Workbench Basic Simulation Capability Model Editors Broker SBML Support ?
Application Application SBW Broker SBW Interface SBW Interface SBW Interface Application Message Passing Architecture
SBW Broker • Small application programming interface (API) • Minimize the amount of work necessary to implement • - Libraries implement inter-program communications • - A registry of services for applications to query • - XML-based model representation (SBML) Programmer’s Perspective - Modular, distributed, broker-based architecture Uses a simple lightweight binary TCP/IP communication protocal
SBW Broker Programmer’s Perspective Language Independent C/C++, Java, Delphi, .NET (C# etc.), Matlab, Perl, Python. Broker is Platform Independent Windows, Linux and Mac OSX
Message Structure - Messages are passed as binary streams via TCP/IP - Blocking and non-blocking calls - Exception handling built-in Supported types in the payload: Byte, Boolean, int, double, string, complex, arrays, lists Language Independent: C/C++, Java, Delphi, .NET (C# etc.), Matlab, Perl, Python.

Building Matlab Services Example - Matlab function y = myAdd (a, b) %SBW module SBWMath %SBW service myService %SBW method myAdd service myService sig=“double myAdd(double,double)” y = a + b Calling SBW from Matlab CLI sbwconnect; getSBML = sbwGetMethod (‘JDesigner’, ‘model’, ‘string getSBML()’); sbwStr = sbwCall (getSBML);
A Web Application is provided that allows every SBW Module to be wrapped up in a Web Service: Web Services from SBW/BioSPICE Web Service Generator web page available at http://134.173.97.95/sbwwebservicecreatorinterface/webform1.aspx

Dynamically locate services in a given category Categories • Categories permit SBW applications to recognize standard interfaces • in other SBW applications. We currently have three defined categories: • Translation • Analysis • Simulation
Translation SBW applications that define the translation category are capable of translating SBML into some other format (eg Matlab, XPP) and returning the translation to the caller. Categories Analysis SBW applications that define the analysis category are capable of accepting an SBML model and by implication are capable of doing ‘something’ with the model. Simulation SBW applications that define the simulation category mean they support the simulation API.
Categories permit users to ‘move’ seamlessly from one application to another taking with them the model under study User Experience

Implements the analysis category. The tool is used to discover whether a particular model has the potential to display oscillatory or bistability. Specialist Modules: Bifurcation Analysis Tool
Specialist Modules:Emery Conrad’s Oscill8 Interface Bifurcation tool begin developed here at VT can interface to SBW. Implements the Analysis category so that models can be accessed from SBW.
Specialist Modules: Structural Analysis Tool Implements the analysis category.
Specialist Modules: Frequency Analysis Tool Implements the Analysis category and permits the frequency response of a model to be determined.
Specialist Modules: Stochastic Simulators Implements the Analysis category and permits models to be simulated using a stochastic solver. Support additional analysis such as PDF generation, Power Spectra, autocorrelation, population metrics
Generic Simulation Interface Any simulator that implements the Sim API (even level 1) will automatically be able to use the interface via this generic simulation interface. Those API methods that are not supported are disabled in the interface.
Non-GUI Modules • LAPACK • CVODE • NLEQ • Structural Analysis Algorithms • Metabolic Control Analysis including Frequency Analysis • libSBML • Translators • Autolayout • Basic Optimizers of time series data to models
We use this tool to take raw SBML and generate SBML containing the layout standard that is being developed by the SBML community. Uses a spring and mass model to determine layout. Has specific rules for determining Bezier orientation and Includes a gravity field to main cohesion of disconnected sub-graphs.
