[Ifeffit] Error using Atoms

Hi Adam,

I opened the cif file you provided and Artemis/Atoms immediately gave the
atoms.inp file attached.
Running Atoms gave the feff.inp....I don't see a problem.

Could you provide more detail on how you achieved this erroneous result?
i.e. step by step...
e.g. I opened Artemis v0.9.25
I clicked 'add' under Feff calculations
I selected Rh.cif and clicked open
et voila! Much humble praise to Bruce...

-R.
