Linear Combination Fitting problem
by Iuliia Mikulska 13 Sep '15

13 Sep '15

Hello, I'm using Demeter 0.9.21 on Windows 7 (32 bit). I encountering a few problems with Athena. So I wonder if it can be solved in future releases. 1. The names of my spectra are quite long (around 40 characters). The first problem is when I try to import data from Athena project file: appears "Import from Athena project file" window. In this window I can see the name of the spectra only partially and this window can not be resized. So my first question is if the "Import from Athena project file" window can be done resizable? 2. I'm using Athena to perform Linear Combination Fits of my spectra. As I said, the names of my spectra are quite long, so to see the full name in the Athena I need to resize the window. The resizing works fine, but if I change the "Main Window" to "Linear Combination Fitting" then the window of the program resizes back to the standard size and I need again to resize it to see the full name of the spectra. It happens each time when I'm using "Data menu" to access different data processing features. 3. When I performing Linear Combination fits, the results of the fits can not be saved into project. This option was perfectly working in old Athena. Here are steps how to reproduce this problem: 1. I chose the spectrum which I would like to fit with standards. 2. Then I chose a few Standards. 3. Then I press button "Fit this group". 4. Now in "Fit results" tab you can see the results of the fit. Up to this step everything works fine. Now I need to fit next spectra. So I choose next spectra in group list and then I repeat 2-4 aforementioned steps. I again get the proper fit. The problem comes when I would like to check the fit which I did for previous spectrum. So in group list I simply choose the previous spectrum, but "Fit results" tab is empty. "Standards" tab shows the standards used for fit of second spectrum. So you can access the results of the Linear Combination Fitting only immediately after fitting. As soon as you move to another spectrum, fit results for previous spectrum are lost. If you need more information, please let me know. Best regards, Iuliia Mikulska

Spline range and FT range
by 이국승(에너지환경소재연구팀) 01 Sep '15

01 Sep '15

Hi everyone, While I was processing my data, I found that the FT features are changing as I change the spline range. I think the change is severe as my data contain a lot of noises at high-k regions (above 12k). The change is remarkable even when FT range is fixed and even when the spline range is far from the low and high limits of FT range. When data are imported into athena, the defalut values for spline ranges from 0 to the end of measured data and the high limit of FT range is set to a value of the high limit of spline range minus 2. There must be a relationship. Could anyone explain these things and general rules for setting the spline range? Thank you in advance. Best wishes, Kug-Seung Lee ________________________________ Kug-Seung Lee, Ph. D.

Re: [Ifeffit] Error in Running XANES on FEFF8.4 for Cobalt based cluster
by Joshua Kas 30 Aug '15

Hi Ganesh, It is common to see the WARNING: TWO ATOMS VERY CLOSE TOGETHER. CHECK INPUT. warning from feff when you have H atoms since the bonds tend to be very short. However, these are not the ones that are causing the problem. These warning can be ignored if the structure is reasonable. If the structure at the bottom of this email is the input structure that you used, then there is indeed an oxygen atom that is less than 0.1 angstrom from a carbon atom, which is of course unphysical. That is probably what is causing the problem, however, there are some other things that could be causing problems as well. In particular, there are what I like to call "floating atoms" in your file, i.e., single atoms or several atoms that are disconnected from the rest of the cluster. I am sending a new input file below that has fixed this problem. I deleted the O atom that was too close to the C atom, and deleted all of the structure that wasn't connected to the central atom by a string of bonds. You might worry about weather the C or O atom is the one that should have been deleted in the structure, but you can always test using both possibilities. I doubt that it will make much difference since C and O look pretty similar, and the O atom is pretty far from the Co. Also, the H atoms look a bit messed up, but I don't think that will make much of a difference either. You can check by taking the H atoms out and running and see if the results change much.

Re: [Ifeffit] Error in Running XANES on FEFF8.4 for Cobalt based cluster
by Ganesh Subramanian 28 Aug '15

28 Aug '15

Dear Bruce, Thanks for the response and sorry for the delay in getting back to you. I retried the FEFF simulation using structural information from another article (Randaccio, Lucio, et al. *Inorganic chemistry* 39.15 (2000): 3403-3413). The structural data from this article seems to be widely used by many others in simulating for optical absorption. But here with FEFF, I still run into the same issue of "ATOMS VERY CLOSE TOGETHER" and a couple of other issues. With two different articles suggesting smaller bond distances for a few of their atoms, it seems like the distances are what they are. I have attached the log files and input file for this trial run. Is there any way to circumvent this error without altering the structure ? Thanks, Ganesh > From: Bruce Ravel <bravel(a)bnl.gov> > To: XAFS Analysis using Ifeffit <ifeffit(a)millenia.cars.aps.anl.gov> > Subject: Re: [Ifeffit] Error in Running XANES on FEFF8.4 for Cobalt > based cluster > Message-ID: <55BA3978.4080801(a)bnl.gov> > Content-Type: text/plain; charset=windows-1252; format=flowed > > On 07/29/2015 06:01 PM, Ganesh Subramanian wrote: > > 1. *Using the FOLP card*: The actual cluster size is about 180 atoms > > extending upto 18 A in radial distance from the central cobalt atom.

Re: [Ifeffit] XANES simulation K-edges
by Joshua Kas 19 Aug '15

19 Aug '15

Hi Debora, The edge energies are very difficult to calculate, and FEFF only calculates them to roughly 5% accuracy. In this case the accuracy is actually much better. However, relative edge energies between different systems may be more reliable. Most comparisons between theoretical and experimental XANES allow for a shift of the edge to align the spectra. If the comparison is of several systems, a single shift should be used for all of them.

XANES simulation K-edges
by Debora Meira 19 Aug '15

19 Aug '15

Dear all, I'd like to know which kind of concern I should have for feff to simulate the XANES for K-edges. I'm asking because I'm trying to simulate Sn K-edge and I have around 30 eV energy shift for the edge position. Can it be related with a wrong parameter for one of the cards? Thank you, Debora Meira

MacPorts now contains Demeter 0.9.22 (and requires Perl 5.22)
by Fowler, Joseph W. 14 Aug '15

14 Aug '15

Dear Bruce: Wait a minute! In fact, I updated the Mac Ports package demeter within the last two weeks to use Demeter version 0.9.22. Mac users might want to use the latest version and should consider doing a "port self update && port upgrade demeter". Users who installed the development version port called demeter-devel will also land on 0.9.22 if they upgrade to the latest. Note that the latest Mac Ports version is known as 0.9.22_1, where the revision number _1 corresponds to the upgrade from Perl 5.16 to 5.22 (which the MacPorts team is pushing on). For many users, there will be numerous dependency upgrades when you upgrade to 0.9.22_1, but I found they took only a few minutes in my particular case. This change in Perl versions could conceivably cause problems, but I haven't heard of any. Best wishes, Joe Fowler (MacPorts maintainer for demeter) ________________________________ From: Bruce Ravel <bravel(a)bnl.gov> Sent: Tuesday, August 11, 2015 6:55 AM To: XAFS Analysis using Ifeffit Subject: Re: [Ifeffit] Energy shift after deglitch I don't see the behavior you describe when I follow your recipe.

La2Zr2O7 EXAFS fitting
by herve muguerra 14 Aug '15

14 Aug '15

Dear All, First of all, I am still very new in EXAFS analysis, so please excuse me for any misunderstandings. My sample is a crystalized La2Zr2O7 thin layer (thickness = 100 nm) on a NiW substrate and we have realized EXAFS measurements by grazing angle under primary vacuum at Lathanum L3 edge (ESRF, Grenoble, France). My objectives are to establish the local distortions due to the different constraints in the oxide thin layer. The La2zr2O7 crystalized in a pyrochlore structure (SG = Fd-3m ; a = 10.78A). First scattering path La-O2.1 2.3352A La-O1.1 2.6453A But I have a problem: I observe the first peaks at 1.28A and 1.80A on the EXAFS spectra as a function of R. How do you explain this feature? Can you point me in the right direction for these issues? I attached the project file La_80_LZO_1000.prj of my sample: LAHM045 to LAHM50 = 6 different scans La_80_LZO_1000 = Data merge Thanks Best regards Hervé Muguerra
