<DIV><FONT size=2>Dear gmx-users, I used anisotropic p-coupling for lipid
bilayers and annealed the system from 330K-300K at the ratio of 2 degree/ns.And
the x dimension and y dimension increased with time in the whole
procedure, but actually the area/lipid should decrease when tempreture
decreases. I think there may due to the P couple parameters I used. Now I write
them here:</FONT></DIV>
