If you are interested in time evolving simulation and analysis on biochemical networks, we recommend you to install the Systems Biology Workbench (SBW) and SBW-powered softwares before you install CellDesigner (*).
Please check http://www.sbw-sbml.org/index.html and download the software from Software/Download section.
(*) Currently, (Sept, 2004) SBW is available on Windows and Linux.
** For SBW for Mac: although it is not the official version, we have tested the SBW for Mac OS X version available at the following site: http://public.kgi.edu/~cwellock/software.htm
To install SBW and SBW-powered software:
CellDesigner 2.1 requires SBW 2.0. Follow the installation instructions.
If you would like to use CellDesigner alone for the time being, you can postpone this step until you need simulation and/or analysis.
