Dear All,
I am using NAME to simulate the gp41 fusion peptide interaction with POPE. I
was wondering whether I need to solvat the model after inserting the peptide
into the lipid bilayer. Since the POPE model built from the membrane package
with water molecules on both ends, I think I do not need add more water in.
But when I tried position-restrained md after energy minimization, it gave
the following information and said margin was to small to partition the
system. Then I set this value to 8 increasingly to make md run, although
extremely slow.
ENERGY: 0 79.6035 1031.5629 1068.2365 4.9426
-15999.2418 -709.9323 0.0000 0.0000 -99999999.9999
-99999999.9999 -99999999.9999 -99999999.9999 -99999999.9999 -99999999.9999
-99999999.9999 -99999999.9999 147220.5786 -99999999.9999 -99999999.9999
Could anyone tell me how to set the Margin value correctly? Many thanks.
sincerely,
Longzhu Shen
