Mac installation error "Failed to build demeter"
by Rebecca Goncalves 05 Dec '19

05 Dec '19

Hi all, I'm getting this error message after entering the command "install xorg-server demeter": [image: Screen Shot 2019-12-02 at 9.52.07 AM.png] Has anyone encountered this issue when installing the program on a Mac? This is what the end of the suggested log files reads: [image: Screen Shot 2019-12-05 at 8.06.09 AM.png] Thanks, Rebecca

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
by Park Gyuchul 21 Nov '19

21 Nov '19

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
by Gentle, Cecilia M 20 Nov '19

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.

Including MS paths with an aggregate feff calculation in Artemis
by Jamie Hart 15 Nov '19

15 Nov '19

Dear mailing list subscribers, Is it possible to perform an aggregate feff calculation in Artemis, and then perform a fit using multiple scattering paths? It appears that the aggregate feff calculation is able to successfully compute MS paths, but Artemis will not let me include these paths in a fit. I am only able to perform an (aggregate) fit using single scattering paths. Please let me know if there is anything I can do to perform an aggregate fit with MS paths. Thank you, Jamie

Installation problems for Demeter on Ubuntu 16.04
by Jo Melville 14 Nov '19

14 Nov '19

Hello all, I am having some troubles successfully building Demeter from source on my Linux machine. All dependencies appeared to install correctly -- a few errors pop up upon running ./Build test (full error report attached), but as best I could discern, the errors produced were the same as those reported in this recent message <https://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg06782.html> ( https://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg06782.html ). Athena appear to install correctly and even start correctly, but upon attempting to import *any* data file into Athena, the following error message pops up (screenshot also attached): > 03:50:59 PM: Unknown warnings category 'experimental::script_run' at > /usr/share/perl/5.22/warnings.pm line 254. > warnings::Croaker("Unknown warnings category 'experimental::script_run'") > called at /usr/share/perl/5.22/warnings.pm line 332 > warnings::unimport("warnings", "experimental::script_run") called at (eval > 2455) line 1 > Pod::Simple::BlackBox::BEGIN() called at (eval 2455) line 1 > eval {...} called at (eval 2455) line 1 > eval 'no warnings "experimental::script_run";

As a result, though the program is (barely) usable, it is very unstable and prone to crashing without warning, causing frustrating data loss. I'm sure that this is due to some fault on my part during the installation process, and would welcome any guidance on how best to approach this issue.

Bug in Artemis
by Natasa Diklic 12 Nov '19

12 Nov '19

Greetings! I encounter an issue for which I find no explanation so far. When I try to export data and fit in k weight 2, the data gets exported in k weight 3 all the time. I can see that Artemis k weight is 2 but Artemis output k weight is 3. Everything was working properly until today. Does anyone knows how to change this Artemis output k weight? Thank you very much in advance! Natasa
