The manual is wrong and I changed the lyx file.

The pdb file I used was generated by sander (the QM region of a QM/MM run). The residue name was printed in the wrong column, this is fixed now.

This works for a simple test. Default residue name is INT in this case. It fails, however, for the Zn complex.

All the best,
