Hi All,

I would like to announce the availability of a new program developed within our 
lab for membrane analysis, which we have named GridMAT-MD.  The program measures 
bilayer thickness across the membrane, projected in the plane of the bilayer, as 
well as area per lipid.  The program *does* account for the presence of membrane 

The algorithm and validation have been accepted by the Journal of Computational 
Chemistry, and the article is now in press, although it has not yet appeared in 
electronic format online.

The program is written in Perl, and has been tested under all the major 
operating systems.  Currently GridMAT-MD only supports the input of .gro files, 
but we expect to expand upon this shortly.  Please feel free to download 
GridMAT-MD and test it; we are offering it for free under the terms and 
conditions of the GPL:


We ask that you fill out a simple form when you download it, mostly to satisfy 
our own curiosity to know how many people are downloading it.

If you have any questions about usage or if you run into any problems, please 
feel free to contact any of the developers, whose contact information can be 
found at the GridMAT-MD site.  The tarball contains a PDF users' guide which 
should address many questions that may arise.

Thanks, and we hope you enjoy our little program.
