  • GROMACS 2018.6. GROMACS is a versatile molecular dynamics package. A thorough treatment of GROMACS can be found on the Compute Canada page.Here is a sample Niagara run script:
  • gmx mdrun is the main computational chemistry engine within GROMACS. Obviously, it performs Molecular Dynamics simulations, but it can also perform Stochastic Dynamics, Energy Minimization, test particle insertion or (re)calculation of energies. Normal mode analysis is another option. In this case mdrun builds a Hessian matrix from single conformation. For usual Normal Modes-like calculations, make sure that the structure provided is properly energy-minimized.
  • gmx_mpi grompp -f em.mdp -c system.gro -p topol.top This command will generate a set of files namely: mdout.mdp, topol.tpr. This *tpr is used to execute the run. And then run it using the command: gmx_mpi mdrun -s topol.tpr This run will provide an energy minimized configuration file “confout.gro” for the system along

  • gmx grompp can be used to restart simulations (preserving continuity) by supplying just a checkpoint file with -t. However, for simply changing the number of run steps to extend a run, using gmx convert-tpr is more convenient than gmx grompp. You then supply the old checkpoint file directly to gmx mdrun with -cpi.
