Re: [Ifeffit] Not possible to install Larch MacOS X 10.12.6 via anaconda (see report)
Hello, I already had this issue and it was related to the python version (6/7 months ago with python 3.8, and then it worked with Python 3.7, but I was thinking it was fixed since).

[Ifeffit] Se reference XANES
Hello everyone, would anybody have a reference XANES spectrum of Se in Selenocysteine or of Se in bacteria ? Thanks a lot in advance for your help.

Re: [Ifeffit] Consult a few questions about XAS data analysis

I would suggest you to take a look. https://bruceravel.github.io/demeter/documents/Artemis/index.html [2] Good luck! -- Regards, Guanghui At 2017-11-14 14:21:38, "Jun Ge" <gejun1...@gmail.com> wrote: Hi Bruce I'm a learner for XAS data analysis because of the need of scientific research. I have been to SLAC in San Francisco three times last year and collected some XAS data of samples and models in Beamline 7-3. This summer, I began to learn how to analyze these XAS data. My professor used to use WinXAS to analyze data. But this time he asked me to learn Athena. He thinks use two different softwares can double check the result. After the data pro-processing, including background remove and data normalization, etc., I save each spectrum in the form .txt. However, IN THE SAME ENERGY RANGE AND SAME FILE OF SAMPLE AND MODELS, THE RESULT OF LCF PERFORMED BY WINXAS AND ATHENA WAS TOTALLY DIFFERENT! I try to solve this problem for a long time but no progress was made. So I turn to you and Ressler (the author of WinXAS) for help. I guess may be the algorithm is different between your Athena with WinXAS, but I'm not sure. With great experience in XAS data analysis, I think it's easy for you to solve this problem, isn't it? By the way, I DON'T KNOW HOW TO FIT THE COORDINATION NUMBER IN ANOTHER SOFTWARE CALLED ARTEMIS in the software package of Demeter. I was told by Artemis that the coordination number can only be a number not alphabet. So I have no idea how to do this (yeah, I'm really a noob orz). And I don't know how to set the parameter more correctly to run a excellent Feff fit. So could you please help me? Finally, I WANT TO LEARN XAS DATA ANALYSIS SYSTEMATICALLY. SO COULD YOU PLEASE RECOMMEND ME SOME REFERENCES LIKE BOOKS OR PAPERS? Anyway, thanks a lot for your help and your precious time!
