=Data Analysis

Install 'feff'.

Install the full 'Demeter' package, that includes the 'Athena' program.

These steps should be done on a terminal, using feff.

These steps should be followed in Athena, from your Virtual machine.

Open Athena.
Import chi.dat.
Select chi(k) as data type.
Click in "replot".
Select the element and edge. (i.e., Pd, K-edge).
Edit k-range [3.0;14.0], dK=1.
Select plotting k-weights: 3.
Apply a forward Fourier transform.
Change plot to R-space, Magnitude-Magnitude. Select and unselect "real part" to update the graph.
In the graph window, clic on file > save current group as > chi(R).
Save the file as .dat inside your Windows virtual machine. Then move to the shared folder to do the analysis.
