Did anyone upgraded to SeaLion aka Mavericks (MacOS 10.9)
by Mangold, Stefan 27 Oct '13

27 Oct '13

Dear all, one question to the early adopter. Did anyone tried ifeffit already on Mavericks? Is there any known issue beside the X11/Quartz issue? I have it installed ifeffit on MoutainLion with the know trick to "emulate" the old X11 (was on the mailing list).

Artemis Software Issue
by James Apollo 26 Oct '13

26 Oct '13

Hello, Bruce and co I am a user of extended xray edge EXAFS spectroscopy and I have what I hope is a well formulated question regarding your software that you have developed. I recently downloaded a fresh copy of Iffefit from the CARS website, but the same issue continues to persist. In version 0.8.012 of Atena, I have noticed that if I ever close the "graphics window #1" the program alerts me that "the window was closed" and the software shuts down. Afterwards, I cannot restart the software no matter how hard I try. I have lost a great deal of my extended xray XAFS and XANES work from this aggreviating software issue. Is there some kind of patch I can download? The updates don't seem to work when I startup the software. Is there a newer version of the software I could use? Please let me know how to fix the problem. Thanks!

Problem with PCA tool in Athena
by Ismael Graff 25 Oct '13

25 Oct '13

Dear fellows, I have an issue with the PCA tool of Athena (using 0.9.18 version of Demeter, windows XP sp2). When I try to target-transform a standard/model compound the program simply ignores my choice of standard. The target transform is applied to the first sample file that I have used to get the different components, even having highlighted the standard compound of my choice. Also, there is no output for the TT coefficients in the text box. Is it a problem of my Demeter installation? Has anyone had the same issue? All the best, Ismael. -- ************************************ * Ismael Graff * * * * Universidade Federal do Paraná * * Departamento de Física, CP 19044 * * 81531-980, Curitiba, Brazil. * * Tel (office): +55 41 3361 3278 * * Tel (Lab): +55 41 3361 3427 * * Fax: +55 41 3361 3418 * * http://fisica.ufpr.br/graff * * * * "DOCENDO DISCIMUS" * ************************************

Charles, It is a bad use of my time to answer questions about the software other than on the mailing list http://cars9.uchicago.edu/mailman/listinfo/ifeffit/ You'll notice this email is CCed to the mailing list. Any further conversation on this topic must use the mailing list.

I've answered this question over a billion times times on the mailing list. Ifeffit, the backend Athena uses for its XAS functionality, is written in Fortran. Fortran has static memory allocation. As normally delivered Ifeffit can handle about 60 groups, given the way Athena uses memory. You have two options. (1) Compile Ifeffit to use more memory. Instructions can be found by searching the mailing list. (2) Live with the fact that you cannot do 200 spectra at a time. As Matt has pointed out many times, Larch will fix this problem. The day when Athena can use Larch is fast approaching. I'm getting there, but I have a lot of things to do each day. So it takes time.

FW: Problem opening Demeter in Windows - doesn't work at all

Dear Bruce, Regarding my earlier mail this week, the log files of my problem. Also, when I go to command window in Windows 7, it says that it can't find the path specified. What should I do? Should I fix the paths and if yes, how do I do that?

calculating particle size from coordination numbers
by Georges Siddiqi 24 Oct '13

24 Oct '13

Hi All, I'm trying to use EXAFS data I have of Cu nanoparticles dispersed on SiO2 and ZnO to calculate their particle size. Searching the archives, i've come by these topics and papers, which have helped immensely, but I'm still a little bit in the dark about the specifics of the fits: http://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg02994.html http://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg03430.html http://pubs.acs.org/doi/full/10.1021/jp012769j http://pubs.rsc.org/en/Content/ArticleLanding/1999/CP/a904654b#!divAbstract So these discussions and papers make it clear that CNs for the 2nd or 3rd coordination shells will give a more accurate picture of the particle size (and even shape). Also, just comparing SO2s between a foil and the sample isnt the most accurate. My initial thought was to get a good fitting model on Cu foil, obtain coordination numbers which are very close to 1, then apply that same fitting model to the Cu nanoparticles (for the Cu-SiO2 species we have TEM data I can again calibrate myself with) However, my specific problem is getting reasonable coordination numbers for the Cu foil. - I can set the SO2 to 1 and get a very good fit for the data, but this is not useful for the nanoparticles - I can give all paths the same SO2 variable, and get a fitted value close to 1, but this isnt useful for comparing first and second shell CNs, as the ratio will always be the same. - And finally, when I try to give each scattering shell its own independent CN, I again get a good fit, but while the first shell SO2 is close to 1, the 2nd shell value is closer to 1.5 I've been playing with which variables are the same between paths, etc, and I can get more reasonable numbers, but the problem then becomes that I cant easily justify my fitting model. Attached is my Artemis file for Cu foil. Any help or suggestions with how to proceed (specifically with how to group variables) would be much appreciated. I apologize in advance if i'm asking about a topic that's been covered extensively. thanks, Georges Siddiqui

Problem opening Demeter in Windows - doesn't work at all (Arjen van Veelen)
by fred.mosselmans＠diamond.ac.uk 22 Oct '13

22 Oct '13

Hi Arjen the most common cause of this is the lack of a directory for the log file for either artemis or athena to write to. in windows 7. see the link bruce sent. if that directory doesn't exist ( or for some bizarre reason they cant write to it) ,neither program will create it and when you attempt to start them a "dos" window " opens then closes as it finds it cant create the log file. Obviously there could well be a different reason but the symptoms you describe are associated with this problem.

Athena: Target transform function not working
by John Hayes 17 Oct '13

17 Oct '13

Hi All, I am trying to use Athena to do some PCA work and am having trouble getting the target transform analysis to work. When I click the target transform button no TT coefficients are produced and only a residual that is shaped like the original spectrum to be transformed is plotted. This seems to happen for all of my standards. (For my data in norm3.prj I am doing the PCA on all the spectra that start with TMF and trying to target transform the other spectra.) I have also tried this with the cyanobacteria data in the XAS-Education folder (also attached) to ensure it wasn't just a problem with my data. I am still have the same problems with this file as well. The dathena.log file and screenshot come from trying to target transform using this file. I am running a 64-bit version of Windows 7 and am running the 0.9.18 version of Athena. Thank you for any help you can provide! Cheers! -- John Hayes The Grosvenor Group Dept. of Chemistry University of Saskatchewan “Somebody told me it was frightening how much topsoil we are losing each year, but I told that story around the campfire and nobody got scared.”

Renaming groups in Athena
by George Sterbinsky 17 Oct '13

17 Oct '13

Hello, I am writing to report what I believe to be a bug in Athena. In the attached project, there are two groups, a main group and a reference group. Changing the name of the first group does not change the name of the reference group. Changing the name of the reference group separately doesn't work well either. This results in an extra "Ref" being added to the beginning of the group name, which cannot be deleted. This happens every time one changes the name of the reference group, which can result in quite a long name for the reference. Let me know if any further information would be helpful. Thank you, George
