Hi :
   I am a graduate student in Sichuan university from China. I have some
puzzles as following: I want to calcuate the binding energy of residues
after calculating the integral binding energy of complex successfully. In
my input files,x-wat-com.prmtop, x-wat-pro.prmtop ,x-wat-lig.prmtop are the
prmtop of complex ,receptor and ligand respectively. And in my system , the
number of atom for complex, receptor and ligand  are 4521, 4484 and 37
respectively. The dielectric constant of the composite solvent in my system
is 56.97.
  My problem is that I can successfully calculate the binding energy
through the input file of coords.in and binding.in.in. However, I can not
achieve the calcuation of residues through the input file of coorsd.in and
resid.in.
   I am looking for you replay and will be very grateful for your
kindhearted.
The three  input files  are as following:
