The Systems Biology Simulation Core Library (SBSCL) provides an efficient and exhaustive Java™ implementation of methods to interpret the content of models encoded in the Systems Biology Markup Language (SBML) and its numerical solution. This library is based on the JSBML project. It can be used on every operating system for which a Java Virtual Machine is available. Please note that this project does not contain any user interface neither a command-line interface, nor a graphical user interface. This project has been developed as a pure programming library. To support the MIASE effort, it understands SED-ML files. Its abstract type and interface hierarchy facilitates the implementation of further community standards, such as CellML.

Getting started

For users

For an introduction on how to use this library for simulation, please refer to the file. There you can find explanations on how to simulate different models and code snippets, including the links to the complete code examples.

For developers

To start working on SBSCL, you should first clone the repository and then refer to which gives instruction to run maven build. Once a maven build is ran, the binaries will be generated in the target folder. This folder will also include a JAR files of the simulation core library to work with.

For an introduction on how things currently work in SBSCL to simulate different models, please refer to the sequence diagrams present in the /dev/diagrams/ where you can understand complete workflow of the library. Once you get familiarized with how things work, please open the javadoc homepage where you can find the complete information about the library properly documented. For formatting the code-base, please refer to formatting-guidelines.

Import SBSCL into your project via Maven as follows:


See Releases and Maven Central for the most recent version number.

Example Code and Demos

A Demo Repository provides a few use case examples and an exemplary POM file that helps setting up the project.

Further examples can be found directly within this repository in the Examples Package, including:

Comparison to Similar Libraries

To compare SBSCL to other simulation engines and to benchmark its predictions and results, a separate project, SBSCL simulator comparison, is available.
