Thanks a lot Elaine,
 I really appreciate your  time  and help. Seems like playing with metal is tricky but not difficult. Thank you.

I forgot to mention one more thing about that attribute definition
file.  It has #0:154.het on each line, which happens to specify the
HEM residue in 1a6m.  You could just edit the text to replace each of
those with :hem (since in your structure HEM is probably not residue
number 154).  The first column after the tab is just the same type of
specifier you would use in the command line, so there are different
possibilities that would all work.  You can use the command line to
make sure a specifier works, for example, select an atom with
   sel :hem@hab
to make sure that ":hem@hab" specifies an atom in your structure.
