Hi Bruce, thanks for the help. Looks not so straightforward like L edges. The information has a price. I also found this software: http://www.cells.es/Beamlines/CLAESS/software/xanda.html Kind Regards, euG 2012/1/3

Dear all,

This spring I need to supervise some undergraduate students during a 4-week project in my research group. I would like to introduce them into the world of data processing with athena and sixpack. I would like to find a tutorial for sixpack and some test data on principal component analysis and linear combination fitting before giving them some of my own data. Can anybody help me ? Or anybody else had to teach something similar, any idea would help!

Thank you very much in advance,

Have a great 2012

PJ Sabbe

Hi Pieter-Jan,

The "EXAFS Divination Set" should work as test data, although I haven't tried PCA on it: http://www.xafs.org/EXAFS_Divination_Set

Feel free to contact me for follow-up if you'd like to know more about that set, etc..

Pieter-Jan,

There is a ton of useful stuff and useful links at http://xafs.org/Tutorials, including much written by folks whose names you'll recognize from this mailing list.

Hi all, I am dealing with some spectra of Er and Yb in the K-edge. Does somebody was doing the deconvolution of the spectra in these energies? I will appreciate all the help to treat the spectra in this high energy regions. Kind regards, euG
