VTMC is a program that analyzes area per lipid in protein-membrane systems by the Voronoi tessellation Monte Carlo integration algorithm (T. Mori, F. Ogushi, and Y. Sugita, J. Comput. Chem., 2012). The program is also applicable to simple lipid bilayer systems. VTMC is available for FREE from this web site for researchers at academic and non profit-making institutions. Currently we are distributing the program as a BINARY file, which runs on Linux (32/64-bit) and MacOSX (64-bit) platforms with single-core or multi-core processors.

How to get VTMC

Our program is being distributed free to non-profit making organizations. This is on the understanding that it will not be passed on to any third party. If anyone wants to use the program, get them to contact us. This will help us keep a list of users to be informed about developments. It should be noted that the program is still under development and therefore the responsibility for their use rests with the user rather than us or RIKEN. The user MUST cite our paper in any publications for which the program was utilized to produce, confirm, derive or process data and/or results.

If you agree with all this, contact with Takaharu Mori (software developer) via E-mail. We reply attaching the program and sample files within one or two days. If you do not get it within one week then it may mean that your spam filter, for whatever reason, filters our reply. Please contain the following information in your e-mail.:
