Frequently Asked Questions

CESE is a simulation package for electrophysiology. It allows you to use models of electrical activity of excitable cells — for example, myocytes or neurons. Currently, only single cell models are supported.

CESE allows you to perform simulations, control model parameters, create and execute clamping commands, and perform simple data analysis using the same, intuitive interface.

CESE is not the data analysis software. The set of analysis features is kept intentionally small. It is anticipated that after simulations and, perhaps, simple analysis, data will be exported to 3-d party software for further processing. CESE supports export to ASCII, Axon Clampfit, and NetCDF data formats.

Currently, CESE does not emulate single channel behavior. It is planned for future versions, but for now CESE is suitable for the whole cell current simulations only.

CESE requires JDK/JRE version 1.5 (5.0) or above to be installed.

This application is written in pure Java and was tested under Windows, Linux, Solaris, MacOS X, and AIX. All required 3-d party libraries are included in the distribution.

CESE is linked to the data visualization library (com.simulogic.dataview) that is being distributed under the terms of GNU-GPL2. Hence, the rest of CESE is also GPL-compatible. Certain 3-d party libraries may hold different license. Refer to the specific documentation for details.

Contact us (support@simulogic.com) if you need to dual-license CESE for commercial purposes.

CESE can perform simulations using single cell models (containing both Hodgkin-Huxley (HH) and Markovian current formulations). The typical usage is simulation of action potentials and individual ionic currents. You can visualize model variables, and control them using clamp commands.

CESE is a Java program. You can use your favorite set of Java development tools to program for CESE. CESE has been built against J2SDK 1.5.0. You can build CESE or models using the included Ant build scripts. Refer to the description of the CESE build system.

Thanks to the object-oriented design of CESE, you can create new models by modifying/extending the existing ones. Make sure to check the source code of the models provided with CESE distribution and read the model creation howto.

If you want to create a new model completely from scratch, extend the com.javable.cese. templates.AbstractAPModel class.

Currently, the main limitation of the model API is its inability to support more than one Markovian current formulation in the given model. Therefore, you can use a "mix" of HH model with one current coded as Markovian.

The preliminary support for transformation of CellML (http://www.cellml.org) models to CESE format is available. Limited set of CellML 1.0 features is supported, refer to the CellML and CESE document for status and usage information.

The SBML format support will be added when a significant number of electrophysiological models is ported to it.

CESE is hosted at SourceForge. We provide full access to the CESE source code via CVS repository. The easiest way to help us develop CESE is to obtain a SourceForge account and mail support@simulogic.com. You will be added to the project as a developer and given CVS write privileges.

If you have developed a new model or extended the existing one and don't want to go through the SourceForge registration, follow the model submission guidelines.

CESE contains context help in the JavaHelp format. Press F1 in the main CESE window.
