I am simulating a protein in solution. And after the pre-processing step in GROMACS using grompp, it displays a warning as :
"The bond in molecule-type Protein_A between atoms 1 BB and 2 BB has an
estimated oscillational period of 9.7e-02 ps, which is less than 5 times
the time step of 2.0e-02 ps.
Maybe you forgot to change the constraints mdp option."
What does this mean? And what options do I change in the LINCS constraints?
