[Ifeffit] feff doesn't like cluster

[Juraj Majzlan]

Hello,

I collected As K EXAFS data and created a cluster which
could represent the "probable geometry". I have an ATOMS
file with coordinates of the atoms in a triclinic unit
cell. ATOMS did its thing but FEFF refused to process the
data and generated an error:
 Feff 6L.02
   No atoms or overlap cards for unique pot     1
  Cannot calculate potentials, etc.
 Fatal Error: at RDINP

Then I filled the empty space around the cluster with
hydrogen atoms on a grid, hoping that FEFF would like it
more, but the same error came.

Short of creating a complete structure (of some sort) with
the cluster embedded in it, what can I do to make this
work?

Thank you,

Juro Majzlan
