[gmx-users] Angle restraint of a peptide

[Khuong Truong Gia]

Dear all,

I setup a simulation system that contains a peptide and membrane. The
peptide is in water and I want to restraint the peptide to make it parallel
with the surface of the membrane. How can I achieve this goal?
If the first problem has solutions, then I have the second question is that
if I use pull code to keep a distance from COM of membrane, can I do at the
same time with angle restraint above?

Thanks in advance,
Khuong
