[gmx-users] Should I restrain omega dihedrals or just phi/psi?

[Daniel Bauer]

Hello,

Im working on MD simulations of membrane proteins and want to restrain the
backbone dihedrals of some amino acids. I now wonder if its sufficient to
restrain only phi/psi dihedrals as shown in the manual (
http://www.gromacs.org/Documentation/How-tos/Dihedral_Restraints), or if I
should also set restrains on omega dihedrals?

 (I dont think it matters but Im using Gromacs 2016.1)

Best regards,
Daniel Bauer
