what happened to the website?
by Matthew Marcus 30 Jan '20

30 Jan '20

The http://millenia.cars.aps.anl.gov/ website seems to have gone off-line, which means that WebAtoms doesn't work anymore. Is there a replacement? Of course, I can use the stand-alone Atoms in Demeter. -- Sincerely, Matthew Marcus

color of fonts in demeter
by Ricardo Faccio 29 Jan '20

Dear all After installing Demeter in MacOS I am having some problems related to the color of fonts and background. Since they look identical is diffcult to see and read. How could be possible to change the color of fonts? I am attaching an example.

Hi all, A colleague of mine here at NSLS-II has an interesting post-doc position open right now. https://jobs.bnl.gov/job/upton/postdoctoral-research-associate-in-total-sca… This position is for a person doing total scattering (aka PDF). Strictly speaking, not an XAS position, but perhaps of interest to someone with an XAS background who is looking for a post-doc.

smoothing XAS data
by Daria Boglaienko 23 Jan '20

23 Jan '20

Hello, In what case smoothing of the data is OK? My data have a lot of noise and smoothing really helps (visually). I compared fit done in Artemis for smoothed and non-smoothed data sets and the result is very similar, however when I searched about it online, it looks like it is not recommended. What is a good way to justify it? Thank you! -Daria

PhD opportunity available at IMDEA Nanociencia/University Autonoma Madrid
by dooshaye.moonshiram 16 Dec '19

16 Dec '19

Dear Colleagues, The time-resolved spectroscopy group and theoretical chemistry group at IMDEA Nanociencia and University Autonoma Madrid, Spain is currently looking for a Ph.D student with intention to apply for by the “la Caixa” fellowship (https://obrasociallacaixa.org/en/investigacion-y-becas/becas-de-la-caixa/do…) Deadline: 4/02/2020. The project will consist in studying solar fuel catalysts through static and ultrafast in-situ X-ray spectroscopy and electrochemistry. The main objectives of the project will be to probe the electronic and structural changes occurring near the active catalytic site through time-resolved X-ray absorption, emission and resonant inelastic scattering spectroscopy. The student will also be trained in Raman, Electron Paramagnetic Resonance, and X-ray photoelecron spectroscopy. Quantum chemistry approaches will be used throughout the project’s duration to determine the geometries of proposed intermediates based on correlation of theory to spectroscopic observables. The results of these studies are expected to have a profound impact on modern catalysis research by identifying the critical requirements for water splitting reactions. For further information, please contact Dooshaye Moonshiram (dooshaye.moonshiram(a)imdea.org) or Antonio Picon (antonio.picon(a)uam.es) Best Regards, -- Dooshaye Moonshiram Group Leader IMDEA Nanociencia Calle Faraday 9, 28049 Madrid, Spain https://moonshiram.wordpress.com/

Mac installation error "Failed to build demeter"
by Fowler, Joseph W. (Assoc) 05 Dec '19

Hi Rebecca, I am the macports maintainer of Demeter, and it certainly worked for me when I installed on my desktop Mac. But given your note, I decided to try installing demeter on my Mac laptop. To my surprise, I see the same error that you did. I don’t have a great idea what this signifies. How can ’string.h’ not be found?? If anyone out there can suggest how to fix this problem, I can try to get the macports version fixed. Otherwise, I’m stumped.

Trouble with energy spacing in .nor files Athena
by Berryman, Eleanor (NRCAN/RNCAN) 22 Nov '19

22 Nov '19

I have run into a problem with Athena binning the energies of my imported spectra without being told to. This problem is best explained by example: I am processing XANES data collected around the Cr edge (5989 eV). I load a datafile that has data collected in 5 eV steps from 5789.2 to 5969.2 eV; in 0.5 eV steps from 5969.2 to 6019.2 eV; in 1 eV steps from 6019.2 to 6139.2 eV. In the 'Import Data' popup window (Athena: column selection), the preview of the raw data shows the current energy resolution. The raw data is processed in Athena using column 1 as Energy, column 10 as Numerator, and column 4 as denominator. 'Perform rebinning' is unselected. I save the processed data as norm(E) to produce the attached result, which has data in the following steps: 5 eV steps from 5789.2 to 5969.2 eV; 1 or 1.5 eV steps from 5970.2 to 6018.7; 1 or 2 eV steps from 6020.2 eV to 6138.2 eV. I have used the rebinning feature during import to circumvent this problem. When I rebin, the saved .nor file obeys the rebinned energy spacing. I need to find a better solution than this. I need to find a way for Athena to obey the energy spacing of the imported dataset. Details on my version of Athena: Demeter 0.9.26 Downloaded last week and today. Installation run as user and as administrator. The problem persists even after reinstallation. System details: 64-bit Windows 10 Operating System Thanks in advance for any direction in finding a solution to this problem.

Illinois Tech Synchrotron Radiation Course
by Carlo Segre 22 Nov '19

22 Nov '19

Hello All: Illinois Tech is offering the graduate Introduction to Synchrotron Radiation course once again in Spring 2020. Please see the attached course summary. The course is offered online and it is very straightforward to apply as a non-degree graduate student as late as the second week of classes in January. The online course will be a one (1) credit course instead of the three (3) credits taken by degree-seeking Illinois Tech students. If you are interested or have interested students please contact me for more details on the course or how to apply and register. Cheers, Carlo -- Carlo U. Segre -- Duchossois Leadership Professor of Physics Directory, Center for Synchrotron Radiation Research and Instrumentation Illinois Institute of Technology Voice: 312.567.3498 Fax: 312.567.3494 segre(a)iit.edu http://phys.iit.edu/~segre segre(a)debian.org

selection of pixels by criteria
by E. Rasbury 22 Nov '19

22 Nov '19

I have used larch some for XRF maps. I like the feature for defining ROI's and then looking at the statistics of the data. I have some samples that are an intimate mix of two or more phases and I would like to extract pixels based on a criteria- like high Sr or low Fe, etc, from across a whole map region. I wonder if this feature is available, or would be easy to create on larch? Thanks! E.

no plot window with Demeter on Ubuntu 18.04
by Joseph Zsombor-Pindera 21 Nov '19

21 Nov '19

Dear mailing list members; I've successfully built Demeter from source on my computer running Ubuntu 18.04. Running "dathena", for example opens the familiar Athena window. Once I try to plot something, however, I get no plot window. It appears as if the program has done something, but the window just doesn't appear. I have installed gnuplot-x11. running 'gnuplot -e "plot sin(x)"' produces no window, but 'gnuplot -p -e "plot sin(x)"' produces a plot, and if I just run 'plot sin(x)' within gnuplot, then I get the plot, so it appears that gnuplot itself is working correctly. 'show terminal' results in: terminal type is wxt 0 enhanced I have tried changing the terminal to 'wxt' under preferences>gnuplot>terminal in Athena, which didn't fix the problem. I have also tried changing the terminal to 'qt' and installing gnuplot-qt. This didn't work, so I purged it and switched back to gnuplot-x11. I haven't managed to get gnuplot to run with x11 as its default terminal. It seems that the default terminal of gnuplot-x11 is wxt. I'm not sure if these matter, but when I run Athena, I get errors in the terminal like this: (dathena:16207): Gtk-CRITICAL **: 11:55:29.414: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkCheckButton thanks, Joseph -- *Joseph Zsombor-Pindera, BSc* PhD Student, UBC Chemistry C

about WebAoms

Hi All, I am trying to simulate the EXAFS spectrum of pure molybdenum through FEFF9 software. I got the atomic configurations of molybdenum from molecular dynamics simulations, and I'd like to import it into FEFF 9. In order to do that, I converted lammps file into cif file, and I am trying to convert cif file into feff.inp. I am using Webatoms to convert cif file into feff.inp. The default value of cluster size and longest path is 8 and 5, respectively (in angs). However, when I try to increase the cluster size and the longest path to 10, it stops working, and I got the internal error. I am working with 1024 atoms (8x8x8 cells, bcc crystal structure). Are 1024 atoms too many to deal with in webatoms? or is there other ways to convert cif file into feff.inp? I don't have any problems when I use the ideal cif file (not from molecular dynamics simulations). Sincerely, Gyuchul Park

Re: [Ifeffit] webatoms for large cluster

Hi Gyuchul, Have you tried using Stand Alone Atoms (it comes with the demeter package) instead of webatoms? In my experience, stand alone atoms should not have a problem with 10 angstrom cluster.
