Dear all,
I have a pdb file as following (See attached):

And I use antechamber and gaussian get the following

-----------------------
As we can see, in the prepin file, the last three
atoms was replaced by X, and its parameters are not
complete. When get frcmod file, the frcmod file is
also not complete.
Will you please tell me how can we get the prepin file
so that the prepin file contains the atom type and
charge for all of the atoms in the PDB file?
I am looking forward to getting your reply.
Best regards.
