[gmx-users] Question about applying a restriction on the movement of a molecule in z direction....

[Alberto Sergio Garay]

Hi all

I need to avoid that a solute molecule cross to the other side of my  
lipid bilayer.and I have thought in several alternatives, which I'm  
not sure whether they are posible in gromacs so I decided to ask for  
suggestions.

Could anyone give any possible alternative to restrict the movement of  
my molecule in the z direction only when it reaches a certain z  
distance from, for example the center of the bilayer ?

Thank you in advance.

Sergio
