Hello dear Gromacs users,

I know how to restrain atoms of an structure solvated in water with force
with option "-DPOSRES". However, for my simulation, I need to exclude
position changing from the simulation, in other words, I need to exactly
fixed them. I highly appreciate if any of you can help me with this.

Thank you in advance,
