Dear all,
I would like to simulate a DPPC membrane in gel phase using Martini
Force Field. As stated on
"Simulation of gel phase formation and melting in lipid bilayers
using a coarse grained model", CPL 135 (2005) 223-244
the correct 30º angle chain tilt for DPPC might be reproduced by
reducing the acyl chain spheres volume by 10%.
So far, I have tried changing sigma and epsilon for C1-C1 pair
interaction without success.
The sphere volume or radius is defined by sigma. Epsilon deals with the
strength of the interactions; you do not want to modify it.
Did you try to contact the authors? They might be of better
help!
Best regards
Cesar Avila
