Hi VMD and NAMD users,

I'm very new to VMD and NAMD. I'm now in the process of parameterizing a
ligand molecule. As I came across various a few web tools like paramchem,
swissparam and so on. I have also seen VMD providing a plugin called
Forcefield Toolkit calculating parameters using Gaussian and preparing the
files for MD run using NAMD.

I would like to get a few suggestion points on which one to use and the
advantages and disadvantages over one another.

What if I use one of the mentioned webtools instead of ffTk that use
lengthy QM calculations to obtain the parameters?

Thanks in advance for the suggestions.
