[gmx-users] dppc simulation

[Michael Patra]

Hello!

I didn't experience any problems when I did my simulations of methanol
and water with a DPPC membrane, see http://www.arxiv.org/abs/cond-mat/0408122.
Please check with "trjconv -pbc inbox" whether you actually are having
a problem, or whether you just got confused by the sometime counter-
intuitive results caused by Gromacs' way of assigning lipid molecules
to the simulation box or its mirror image.

Greetings,
