Dear all,
Thanks for the help on my previous questions. I am trying to minimize a
pope membrane (no protein yet, but lipid tails had already been melted)
with water on top and bottom. I have done it previously without problem.
This time when I start the minimization, I get this odd result :

Any help will be very appreciate.
