How to do FEP simulations to calculate the absolute free energy of solvation?

Dear namd users,

Recently I wanna to do some research on the absolute free energy of some small organic molecules using the FEP in NAMD.
But I get in the trouble in how to begin it.

>From the manual I know NAMD using dual topologies to do FEP. So one must define the dual topologies in the PDB file. But
I don't know how to define the PDB file. Does anyone have any experience to do it. Could you send me a example of the files
you use to do simulations.

For a example, I want to do the calculations on CH4. How to define to files used to do simulation?

Thank you in advance.
  

Sincerely yours
