Au-foil (fcc) splitted peak
by grant bunker 29 Jan '12

29 Jan '12

Julian - the scattering amplitudes of all elements have structure in them that are connected to electron scattering (Ramsauer-Townsend) resonances within the backscattering atom. For light elements (e.g. O, S, Fe) they occur at energies that are lower than the typical transform range, so they usually are ignored. For heavier scatterers like Au there are strong minima and maxima in the Au scattering amplitude over the transform range. From a signal processing point of view, these amplitude modulations look like beats, which normally are due to different distances interfering. In the case of Au back scatterers, even if there is only one physical distance, you will get multiple peaks (perhaps overlapping). Mathematically the fourier transform is the distance distribution convoluted with the fourier transform of the amplitude. So, how do you deal with it? First, if you know what's going on that may be enough. Alternatively, if all the scatterers are the same, it's not difficult to divide out the scattering amplitude and subtract out the scattering phase before the transform to obtain an "optical transform", which eliminates the effect you're seeing. I don't know if that is supported by ifeffit but it's not hard to do. This approach is less useful if you have multiple types of scatterers (e.g. Au, S) because if you do the compensation for one type of scatterer it screws it up for the others. Techniques like regularization are probably better in that case. hope that helps grant bunker

SRS data
by Michael Stockenhuber 28 Nov '11

28 Nov '11

Dear all, Thank you very much to the developers for this great software. I have a problem with some old SRS station 3.4 data. I cannot read in original data with athena. I enclose a data file r48683.dat )( Al K- edge). I have installed DUBBLE, but still does not want to read it. I also would like to read in data from station 9.3. This is fluorescence data with a 13 element detector and also includes E0 and E1 and I think Em. I enclose a data file, r94731.dat ( Cu K-edge). Any help would be greatly appreciated. DUBBLE.py reads in station 7.1 data. I enclose a datafile (r66946.dat). All the best and thank you for the help Michael

Hi Matt, Thank you very much. I will have a look at the script and maybe I can modify it. I am not really good in coding but you certainly gave me an idea where to start. Thank you for looking at the files. If I get anywhere I will certainly post. I am sure I am not the only one having to do that :) Cheers Michael >>> Matt Newville <newville(a)cars.uchicago.edu> 18/11/11 3:13 AM >>> Hi Michael, On Thu, Nov 17, 2011 at 5:17 AM, Michael Stockenhuber <Michael.Stockenhuber(a)newcastle.edu.au> wrote: > Dear all, > Thank you very much to the developers for this great software.

First, these files end with a line reading "END OF DATA", which ifeffit doesn't like, but which it can ignore. Second, two of the files (r94731.dat and r66946.dat) do not have data arranged so that one line is one energy point, and they have an inconsistent number of columns per line. Ifeffit usually considers line breaks to be significant. Third, one of the files (r48683.dat) has two lines with '----' starting after a comment character -- ifeffit takes such a line to signify the end of the header. Athena allows file-reading plugins to be written in perl -- I think you'll probably want to consult with Bruce about writing (or having one of these written for these files). Alternatively, you could write a program to convert these files to ones that make ifeffit's limited read_ascii() routine happy. Perhaps DUBBLE.py (I'm not familiar with that) can be made to do this conversion? Hope that helps, --Matt _______________________________________________ Ifeffit mailing list Ifeffit(a)millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit

Hi Thanks to all About the GUI, it is a quick and dirty job so I was a little ashamed to public show it. It is aimed to analyze sequentially big set of data coming from dispersive and qexafs beamlines. Source code and installer for windows are available at the link http://code.google.com/p/prestopronto/ The code is in a very beta stage, so big part of documentation is missing and is not tested extensively, I'm sure that it is still full of bugs. However If someone is interested to tests, modifies, give a look it is obviously welcomed.

feff6l licence
by Carmelo Prestipino 16 Nov '11

16 Nov '11

Hi to everybody I'm currently working to an another GUI to Ifeffit, aimed to large dataset , it is still in beta version and full of bug but some collaborators start to use it . In the installer that I send to them is present the "feff6l.exe" file, to generates phase and amplitudes , but now I have a doubt. Does the feff6l licence allows a generic redistribution? , or have the Horae and the Sixpack packages a special agreement? Thanks in advance Carmelo -- Carmelo Prestipino Sciences Chimiques de Rennes UMR 6226 Campus de Beaulieu, Bât 10B F-35042 RENNES France Tel: (+33) 22323 6531 FAX: (+33) 22323 5959

Re: [Ifeffit] software issues on a 10.1" netbook (Coppage, Ryan H)

Hello Ryan. As Chris suggested, you may want to change the fonts to allow the window to show everything (even if gaining 1/3rd of the screen seems a lot, you might need very small fonts). I don't know about Windows, but in case the file names are similar I can tell you where to do this under linux: in the .horae folder, you want to edit the athenarc and artemisrc config files. This is the only way to change the font sizes (if you go to the Edit/preferences menu in a running athena or artemis session, the message will be that it is the only parameter that you have to change through the config files). Hope it helps.

Hi Ryan, I have the same problem when I use my netbook. The only solution I've come up with is to change the display settings to "Portrait" to open a project file or import data. Then I switch back to "Landscape" view when I'm working with the data. It's not an ideal solution, but it works. Lisa Lisa Van Loon, Ph.D. Industrial Research Scientist Canadian Light Source Inc.
