update for Windows, fixing problems with Athena/Artemis
Hi Folks, I just put up a Windows updater with new versions of Athena and Artemis which (should / seems to) fix the "Athena is stuck" problems seen be various people. Details on what else changed are below. All windows users with Ifeffit 1.2.10 and 1.2.11 should install this update. If you're still using an older version, beware that this update will be binary incompatible with that version, and you should upgrade to 1.2.11 before installing this update. If you've been having troubles with Athena/Artemis "getting stuck" and these persist after installing this update, please let us know!! --Matt =========== This update to Ifeffit 1.2.11 for Windows corrects several problems with the prior release related to building the Athena et al executables against the wrong version of the Ifeffit library. This update includes newly rebuilt executables for Athena, Artemis, Hephaestus, and Atoms. Additionally, the following features have been added to Athena: 1. Filename are sorted when importing multiple files. 2. Corrected a problem related to importing chi(k) data that do not start at 0. 3. Filetype plugins have been added for: - SSRL binary files - SSRL ASCII files - SSRL MicroEXAFS files - files from the CLS HXMA beamline - files from Photon Factory beamline 12C Enjoy!

Hi everyone, If, at your institution, you are behind an internet proxy, you may need to configure your computer such that the Ifeffit updater can find the update that Matt announced last week through the proxy. I know that some folks at Brookhaven and the NSLS have had trouble doing so in the past (myself included). I made a wiki page explaining in detail how I was able to solve this problem without otherwise harming the functionality of my computers. http://cars9.uchicago.edu/iffwiki/IfeffitOnWindows/WinUpdaterProxy Everyone should update. If you have not done so because of a proxy, hopefully that wiki page will help. If your proxy configuration is different, feel free to put that information of that wiki page.

Hi Everyone, I am using Athena peak fitting function to fit the sulfur spectrum of my coke sample. I checked everywhere, but couldn't get detailed instruction for using this function. So, I attached a file with this email to get help. Could you please take a look at it, and tell me if I did the fitting right (in terms of fitting procedure only)? I did the fitting in two ways, and I know both of them have problems. For instance, in the first case, I can't get a good step line and have to cut off the tail of the spectrum. In the second one, peak 1 is way too broad, but if I cut it off, the fitting will be very poor. So, please tell me which way is better, or you have some ideas to improve the fitting. Thank you in advance! Best, Jenny __________________________________________________________________ Yahoo! Canada Toolbar: Search from anywhere on the web, and bookmark your favourite sites.

Hi Jenny,
I would say that method 2 looks better, as the fit over the whole of
the specified fitting range is clearly better. I wouldn't
necessarily say that "peak 1" in this fit -- I'm assuming you mean the
highest energy peak at ~2488.3eV -- is too broad. At that high
energy (definitely into the EXAFS region), the idea of peaks coming
from specific electronic transitions breaks down, and EXAFS
oscillations can be that broad in energy.
It seems that you need this "broad peak" because you're fitting out
past 2500 eV. I think that's OK (that third broad peak may not be a
single electronic transition but is still useful for identifying
species). But, if you'd rather not have to use the broader peak, you
might also try fitting just the two sharper peaks at lower energy, say
out to 2485 eV.
Hope that helps,
--Matt
