This is the sort of question that should be asked on the Ifeffit mailing list,
so I am taking the liberty of CCing my answer there.
I agree that the input file for As2O3 from the database is wrong. It
generates an obviously incorrect list of coordinates. You need to go to the
crystallography literature and find the correct data for that structure.
There is nothing wrong (at least with respect to this question!) with
Artemis. It seems likely that the problem is with the reliability of the data
for As2O3 in the database.
