[gmx-users] starting structure of DLPC lipid bilayer

[David L. Bostick]

In the past I have created a DLPC bilayer from a DPPC bilayer by clipping
the tails of the DPPC molecules.  It's fairly easy to do and if you run it
with pressure coupling in the z-dimension only for a few nanoseconds, the
bilayer thickness converges pretty quickly.  You can then switch back to
semiisotropic coupling and keep running.
