It looks like your pdb file does not follow standard nomenclature, and may
have the atom names in unexpected columns. First, the amide hydrogen should
be named "H", not "HN". The naming of the hydrogens attached to CB in SER
and ALA also are not being recognized.

One common option is to remove all the hydrogen atoms from the pdb file, and
let Amber re-add them with the proper names.
