A few ideas:
This tutorial was written before antechamber and the GAFF forcefield were
developed.
It is still helpful as it shows you the lower level components that must
be thought through as you prepare your calculation.
For detailed receptor-ligand calculations, it is very important to
understand how new atom types are added to the forcefield, the likely
development of new forcefield parameters (bonds, angles, torsions)
required by your ligand, and the calculation of the ligand point charges.
Antechamber may be very helpful to you in development of these parameters.
But for detailed calculations on a single ligand/receptor complex, you
will likely want to perform more detailed ligand parameterization.
