Do you mean: "how can I find the coordinates of residues that are not present
in the PDB file?"
What you need for that is probably a homology modeling program, or something
similar. Amber has a very limited ability to fill in missing coordinates, and
generally assumes that you know what the starting configuration will be. If
CAChe is not working for you, you probably need to figure out what its problem
is, or look into other model-building programs. Without knowing what the
"some missing residues" are, or even how many of them you have, it's hard to
be very specific with advice.
