The package viewer shows the meta data for the package and the available versions, i.e. the history of the parameters. Note that files can differ between versions, in which case the SHA1 checksum after the filename will differ. You can read and add comments for a particular version through the View discussion button on each version.

If you are the curator of a package (i.e. you added it) and you are logged in then you can also edit the package.

Abstract

D-POPG and L-POPG (the bilayer appears to be pure D-POPG).

Lipid parameters of Kukol, JCTC 5 (2009), 615: United atom (UA) lipids
were constructed from the GROMOS 53a6 atom types.

Experimental areas per lipid are reproduced to within 3% for DPPC
without application of surface tension, and 1.5% for POPC.

Parameters were copied directly from the supplementary information available from 10.1021/ct8003468 (ct8003468_si_001.zip)

Version 2 has itp files for Gromacs 4.x, obtained from Andreas Kukol.

Original README:

The .pdb files contain a snapshot of the lipid bilayer after 40 ns of MD simulation.
The .itp files contain the molecular topology for the GROMOS96 53a6 force field.
They are suitable for use with the GROMACS MD simulation software.

All details about the MD simulation conditions and topologies are in the manuscript.
