[gmx-users] DNA orientation restraint

Hi everyone, I am doing a DNA simulation in a long simulation box (the lengthen of z is much larger than x and y). So I want to constrain the DNA molecule lying along the z axis. But I don't know how to realize this in GROMACS. Actually I notice there is orientation restraints in 4.3.5 of GMX
