Be careful in trying to use exactly what the tutorial does with other systems;
specifically, if you're using a different force field, you shouldn't be using
the tutorial's .mdp files.

The list does not accept attachments. If you want to share files, please upload
them to a file-sharing server and provide the relevant URL(s). Include .mdp
files. A full description of what you have done thus far, as well as the output
of energy minimization, is needed.
