[gmx-users] a warning in grompp

[Banafsheh Mehrazma]

dear all;
I am trying to run grompp command and I encounter this:

.............................................................................
WARNING 1 [file topol.top, line 54]:
  The bond in molecule-type DNA_chain_A between atoms 1 H5T and 2 O5' has
  an estimated oscillational period of 9.0e-03 ps, which is less than 5
  times the time step of 2.0e-03 ps.
  Maybe you forgot to change the constraints mdp option.
................................................................................
 however when I use -maxwarn with grompp, it seems like that there is
nothing wrong. Is it OK to continue the simulation with using maxwarn, or
is there some thig wrong that needs to be modified?

Thank you in advance
Banafsheh
