[gmx-users] Forced adsoprtion and desorption of a protein on a surface

[James Lord]

Dear Users,
I am wondering if anyone can help me out with forced adsorption/ desorption
of a protein on surface. I am aware of pulling code in Justin's tutorial
but that is not what I am looking for. I want a simple constant force
(perpendicular to the surface) method to push and/or pull the protein
(center of mass) onto /or from a surface at specific time intervals during
the simulation . Appreciate any comments.
Cheers
James
