Laura,

You need to manually pick three our of the four Fe atoms in the first
molecule to use in the atom selection. How you pick them is up to
you, but there has to be the same number as in the second selection.
You also need to make sure that the Fe and S atoms are in the same
order in both selections. If that's not the case then you'll need to
go and manually reorder the lines in the pdb file to make this so,
otherwise VMD will align an Fe atom with an S atom, which isn't what
you want.

Cheers,
Justin

The spirit of Plato dies hard.  We have been unable to escape the
philosophical tradition that what we can see and measure in the world
is merely the superficial and imperfect representation of an
underlying reality.
