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!

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

Demeter/Strawberry Perl in Windows 8
by Godfrey, Ian 15 Oct '13

15 Oct '13

Hi All, I was wondering if anyone has encountered the following error (screenshot attached) while trying to run Demeter applications (it seems to occur at least for both Artemis and Athena) under Windows 8. I know other members of my group have successfully managed to run Demeter under Windows 8 but have not encountered this message.: "perl.exe - Entry Point Not Found The procedure entry point __gxx_personality_v0 could not be located in the dynamic link library C:\strawberry\perl\site\lib\auto\Wx\Wx.dll" I have run the installer under Windows XP compatibility mode and used the Windows Compatibility Troubleshooter to no avail. I have tried installing the latest version of Strawberry Perl (I have tried both the x86 and x64 version, I have an x64 system) - this changes the symptoms so that the command prompts appear briefly on screen and then disappear. Re-running the Demeter installer than causes the original error message to begin appearing again. I have run all the installers as admin and have tried setting perl.exe both to admin and compatibility mode. I have authorised all UAC prompts that appear. Any help with this would be greatly appreciated.

About ASCII Data Export in Athena 0.9.18
by Shoaib Muhammad 03 Oct '13

03 Oct '13

Hi, I have Mn XAS data and I am trying to export this XAS data by using "File", "Save marked group as" and "norm E". My Mn XAS data shows some spikes around 7150eV other than main Mn K edge peak due to some Fe impurity. So it is hard to fit post edge and I have ticked "Flatten normalized data" to get a straight line post edge. After doing this I can see an almost straight line post edge in the Athena preview graph but when I export ASCII data to plot in OriginPro etc it seems like data is being exported with out "Flatten normalized data". I have attached relevant information. Am I missing some point or is it a software bug? Thanks -- Shoaib Muhammad Department of Energy Science Sungkyunkwan University South Korea
