What Gusatvo (tried to) say:

Use loadmol2 and loadamberparams to get the topology and parameters loaded.
Then say something like this:
x = loadPdb filename.pdb
where "filename.pdb" has the coordinates of both the ligand and the receptor;
(or just the ligand if there is no receptor). Then "saveamberparm x ...."
will give you coordinates that came from the pdb file.
