[gmx-users] separating bilayer leaflets - POPC vs. DMPC and DPPC

If you can prescribe an area and run the bilayer for some time (1-2 ns) in a
constant area, constant pressure ensemble, and then switch to semiisotropic
pressure coupling, this could fix it.  

Dear Dr Bostick,
I quite don t understand what you mean by a constant area,constant pressure
ensemble. Do you mean you assign parameters of 0.0 and 4.5e-5 compressibility
in xy and z respectively under semiisotropic coupling for constant area and
constant pressure? 

And then you shift to 4.5e-5 and 4.5e-5 compressibility in xy and z respectively
for a "proper" semiisotropic coupling?

I was confused regarding this point when you had replied to my earlier question
last month.

Thank you for your time
