Your PDB file does not correpond to the PDB standard in terms of atom
names. The simplest thing to do is get rid of all of the hydrogens, and
let tleap build them back in with the proper names.

Or you can try to edit your input pdb file. "HN" in protein residues
has been called "H" for a very long time. I *think* what your file is
calling "H5T" is really "HO5'", and "H3T" is likely "HO3'".

...good luck....dac
