Dear all,
I've built a Graphene in water topology in order to simulate it. I've
obtained Graphene structure from VMD (Nanotube builder) and I was able to
generate the topology by following the instructions of the tutorial of
Andrea Minoia.

While running the following command:

gmx grompp -f ions.mdp -c 1AKI_solv.gro -p topol.top -o ions.tpr

I recieve as error:

Source code file:
line: 1353

Fatal error:
Atomtype HC not found

Since I am new in Molecular Dynamics simulations, I am asking you to help
me understand where I got it wrong and what can I do to solve this problem.
