I don't quite understand the question, but perhaps an example of an
atoms input file would help clarify. This is taken from the examples
that come with the software:
title YBCO: Y Ba2 Cu3 O7
space P M M M
rmax=5.2 a 3.823 b 3.886 c 11.681
core=cu2
atom
! At.type x y z tag
Y 0.5 0.5 0.5
Ba 0.5 0.5 0.184
Cu 0 0 0 cu1
Cu 0 0 0.356 cu2
O 0 0.5 0 o1
O 0 0 0.158 o2
O 0 0.5 0.379 o3
O 0.5 0 0.377 o4
This can be read directly into Artemis and used to start a feff calculation.
