Hello, On Peter Tieleman's website we can find topologies for various popular lipids. However those seem to be valid for the deprecated GROMOS87 force field. The g96_lipids.itp file is still unavailable. I'd like to run a simulation of 7TM protein embedded into POPC membrane. G43a2x seems to be a reasonable choice for this purpose. I still need the parameters for my lipids. I am aware that combining parameters from different force fields might lead to a disaster, that's why I want to ask you: 1. Do you know any papers where POPC membrane and G43a2 force field was used? 2. If not, is there any way to derive the proper parameters for the force field of my choice using the lipid parameters from Peter Tieleman's website or e.g. the parameters published by Andreas Kukol for G53a6?
Thank you in advance, Christopher
