Building Membrane Systems

Building Membrane Systems is tricky in Amber. A force field for the each component including lipids must be chosen. Various members of the Amber community have developed tutorials, which are listed here. Common methods to build a membrane system include using:

Lipid Force Fields

Please see the force fields page to learn about Lipid Force Fields.

Tools and Tutorials to Build Membrane Systems


By JD Callum

PACKMOL-Memgen is built into Amber. This tutorial uses the CCG MOE GUI for protein preparation (add hydrogens, cap termini, set protonation states). You may have access to MOE or a similar GUI/tool to achieve the same task. PACKMOL-Memgen also has prep options.

Lipi21 and PACKMOL-Memgen Setup


By Wonpil Im

Some people find it easier to set up a system for simulation in Amber using the CHARMM-GUI interface. These tutorials were written by Wonpil Im at Lehigh University. He also has You Tube videos on these tutorials.

10.2. Building Systems with CHARMM-GUI

5.7 An Amber Membrane Simulation Tutorial: Lipid14

lipid bilayer

By Benjamin D. Madej and Ross C. Walker

This tutorial explains how to set up and simulate lipid bilayers with the Lipid14 force field and CHARMM-GUI. This is a more general tutorial that walks you through how to build a system, equilibrate it, run MD and monitor properties.
