Determining errors in R_fit
by Rana, Jatinkumar Kantilal 17 Nov '12

17 Nov '12

Dear Ifeffit users, I have a very simple doubt about reporting the uncertainties in R_fit. In the fit, I have assumed that a bond length changes by a constant fraction, *alpha* such that Delta R = R_effective * alpha and, R_fit = R_effective +/- Delta R I can get uncertainties in the fitted value of *alpha* from artemis. But the question is how to work out the uncertainties in the R_fit. Will it be same as that of *alpha* ?? Thanks in advance !!!

Demeter on windows 8
by George Sterbinsky 14 Nov '12

14 Nov '12

Hello, Has anyone been able to install Demeter on windows8? When I try to open Athena I get the message in attached screen shot. I tried reinstalling as suggested by the message, which did not help. One thing I noticed however was that Perl was not removed by the built in Demeter uninstaller. Any suggestions appreciated. Thank you, George

questions about plotting old fits with demeter/artemis
by Georges Siddiqi 13 Nov '12

13 Nov '12

Hi All, I recently upgraded to the new version of demeter/athena/artemis, and while it is very nice to use, I am thoroughly lost in some areas. In the old version of Artemis, it is very easy to select old fits and plot them compared to the experimental data/new fits. I cannot figure out how to do this in the new version. The tutorial merely says "The history plotting tool is not currently working, making it difficult to write this bit of documentation!" Currently what I do is goto the "history" box of the main window, and goto the "plot tool" tab, but I can only add the 9 first fits to the plotting list. Any suggestions? am I missing something obvious? or is this (as the tutorial implies) a functionality that hasnt been added yet? thanks, georges

About Launching Athena on Mountain Lion (Mac OS 10.8)
by 上村洋平 12 Nov '12

12 Nov '12

Dear ifeffit mailing list menbers, I'm Yohei Uemura from Hokkaido University, Japan. For Mac users, you may know the thread below about not laucning iXAFS under Maountain Lion. http://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg03412.html I don't know any other threads about launching iXAFS.app under Mountain Lion. I've also given up launching Athena and Artemis under Mountain Lion. But, today I found by chance how to launch Athena undr Mountain Lion. The procedure is as follows; 1) Launch XQuartz. 2) type in the xterm of XQuartz "/Applications/iXAFS.app/Contents/ Resources/iXAFS\ Shell.sh" #iXAFS.app is placed in "Application" folder. 3) type "athena" in the xterm, and then I'm able to lauch athena. Does anyone launch Athena or Artemis under Mountain Lion? I would like you who use Mountain Lion try to do my procedure.

spinel XANES calculation by Feff
by Enyuan Hu 12 Nov '12

12 Nov '12

Dear all, I was wondering if anyone had experience in calculating XANES spectra using Feff for the spinel system. The material I was trying to investigate was ZnFe2O4. There were reports in literature that gave satisfying simulation results by Feff so I tried to follow. The feature peaks' positions from my simulation is generally right, but the intensity is definitely wrong. So I guess either someone can give me some suggestion about the getting the intensity right or share with me about his or her spinel XANES calculation experience. My background is mainly in chemistry and material science with general ideas about electronic structure. Any comment or suggestion will be greatly appreciated. Thanks! Enyuan

I think the problem is solved by making a Demeter folder in the application data folder for each user.

Dear all, I'm trying to join the mailing list for FEFF users. A search in Google led me to the the address listproc(a)u.washington.edu. But my attempt to join always failed as my mail keeps being rejected. I noticed the most recent post in this mailist list was from 2005. Is this mailist out of date? can anyone show me the right way? Thanks! Enyuan

questions and storms
by Bruce Ravel 02 Nov '12

02 Nov '12

Hi all, I have received a number of questions and bug reports about the software -- both over the mailing list and via personal mail -- in the last few days. Because of the recent storm here in the eastern part of North America I have fallen a little behind. I will address all the issues sent to me, but I may not respond for several days as I get caught up both at work and at home. If you are waiting for an answer to your question -- please be patient, I won't forget about you.
