We have developed a new web sever called MemGen, that sets up simulation systems of lipid membranes. MemGen is not restricted to specific force fields, lipid types, or MD simulation software. Instead, MemGen works with any uploaded lipid (or amphipilic molecule) in either all-atom or united-atom representation.
Please give it a try (takes only 2 minutes) at http://memgen.uni-saarland.de.
