[gmx-users] Dihedral restraints

Dear gromacs users,
I am working in a system composed by a protein in a solvated box. It is a
coarse-grained model (Martini ff). The protein has an amyloid part
(strand-loop-strand), at first I tried to simulated this without restraints
but the structure collapsed, then I used position restraints as a result it
kept the structure but due to the type of restraint I applied it is fix in
the box without possibility of motion (translate, rotate). I was reading
and maybe using dihedral restraints I can solve this problem. Someone knows
if it is possible?
In summary, what I want is keep the amyloid part in its correct structure
but allow its movement within the box.
Thanks in advance!
