After inserting the protein, the equilibrium box length in the x and y
dimension should be different, so you need anisotropic pressure coupling during
the 1st step. After equilibrium, the ratio of box length in x,y is fixed, so
you can use semi-isotropic method.
Most pre-equilibrated bilayers have (roughly) equivalent x and y box dimensions.
Why do you think they should inherently be different?
In my experience, anisotropic coupling leads to major deformations in the x-y
plane, taking a bilayer that is initially a square (roughly) in the x-y plane
and turning it into a rectangle. I'd be very curious to hear Peter's answer to
this question. I used to use anisotropic coupling, but now I use semiisotropic
exclusively.
