Basic Usage
Preparing Input Files
- Prepare protein structure file (PDB format)
- Generate topology file:
gmx pdb2gmx -f protein.pdb -o processed.gro -water spce
- Define simulation box:
gmx editconf -f processed.gro -o newbox.gro -c -d 1.0 -bt cubic
- Add solvent:
gmx solvate -cp newbox.gro -cs spc216.gro -o solv.gro -p topol.top
Energy Minimization
- Prepare energy minimization parameters
- Run energy minimization:
gmx grompp -f em.mdp -c solv.gro -p topol.top -o em.tpr gmx mdrun -v -deffnm em
Molecular Dynamics Simulation
- Prepare MD parameters
- Run MD simulation:
gmx grompp -f md.mdp -c em.gro -p topol.top -o md.tpr gmx mdrun -v -deffnm md
