## The GROMACS demo

The demo is designed to demonstrate the user-friendlyness of the GROMACS software package. The only non-friendly part is that it requires the C shell to run the script. If your shell is e.g. bash (common on Linux), first start the C shell with the command 'tcsh'. To run the demo, first move to your `tutor/gmxdemo` directory:

| `cd tutor/gmxdemo` |

And then start the demo script:

| `demo` |

This demo handles a complete Molecular Dynamics simulation of a peptide in water, starting from a pdb structure. You will be asked to press return a few times, and to run the trajectory viewer. Please read the instructions as you go along.
