I apologize if it is a FAQ.
I'd like to make some MD simulations of a small molecule (cinchonidine), 
changing solvents and other stuff.
Obviously, I've to compute a new topology for the molecule...
Then, how can I choose the best  FF, considering that gromacs FF is 
deprecated in gromacs 3.3?

I computed the topology using prodrg, then I chose the gromacs FF 
because I used it some time ago for proteins.
Are there other tools to compute a topology from, for example, a 
Z-matrix file?

Thanks,
Gianluca
