Re: [Ifeffit] Launching Athena on Mountain Lion (Mac OS 10.8)

Hello, I had posted a comment/question a few months back when I had initially installed Mountain Lion on my mac regarding iXAFS compatibility with XQuartz and the new OS not supporting X11 anymore. Since then I have received a few comments back and I found one solution to be the best. This was originally sent by Tsu-Chien Weng from SSRL (tsuchien(a)slac.stanford.edu) Please find the following solution below. Once you install XQuartz the rest will be done in the Terminal.app. This is a one time solution and I havent had any trouble thus far with the program. Hope this works as well for everyone else as it did for me. 1. Install XQuartz from <http://xquartz.macosforge.org/landing/> 2. open Terminal.app 3. cd /Applications/Utilities 4. sudo mkdir X11.app 5. cd X11.app 6. sudo ln -s ../XQuartz.app/Contents Thank you, Kyler J.

Fitting EXAFS simulation to experimental
by Carl Brozek 29 May '14

29 May '14

Dear listhost, I'm using Artemis as a front end for ATOMS and FEFF and I would like to build a simulated EXAFS spectrum based on experimental data I have. I know how to generate a simulation based on a .cif or .xyz file, but is it possible to vary parameters in these input geometries to best match the experimental? Has someone implemented this in artemis or matlab? thanks, Carl -- PhD Candidate | Chemistry | MIT SB | 2010 | University of Chicago

Re: [Ifeffit] Demeter on Ubuntu 14.04

Thanks for your answer Bruce. Don't spoil your holidays/vacation for this! I had done the "perl Build.pl" or "./Build installdeps" steps. In fact I tried a clean install with all those steps. Right now, I tried the touch_wrapper you mentionned without success. I also tried an install as root for all the steps: no success either. I'm stuck and it might be something stupid I can't see. When you have some time to have a look, let me know, there's no rush right now.

Demeter on Ubuntu 14.04

Dear members of the list, it's that time of the (Linux) Ubuntu life cycles where you do upgrades and break previously working programs... Upgrading to Ubuntu 14.04 made no exception for me. It also broke the old Hephaestus programs, but I think it is definitely time that I stop being lazy and switch to Demeter. So I'll focus on the Demeter problems. Sorry about the lengthy post full of pasted error messages. -------------------------------------------------------------------------------------------------------------- Context: I'm running Ubuntu 64 bits 14.04. Demeter version 0.9.20. I followed Ubuntu specific instructions found here: https://gist.github.com/3959252 Demeter once worked but I cannot guarantee that it did just before the upgrade to 14.04. After the upgrade, both trying to run dathena or to rebuild the package ran into errors such as: denis@huchet4:~/demeter$ ./Build Building Demeter Perl API version v5.14.0 of DateTime does not match v5.18.0 at /usr/share/perl/5.18/XSLoader.pm line 92.

OK, enough. Let me know if I can try different things to help source the problem. Regards. Denis

Problems in Energy calibration
by Lei Zhong 16 May '14

16 May '14

Dear all, we had beam line time in DESY (Hamburg) and ERSF (Grenoble) for NiMo sulfided supported samples. In DESY we got quite nice foil reference but in ERSF we failed since the third chamber showed problems. Therefore, we have critical issues to do the energy calibration for spectra collected from ERSF. We collected spectra for MoS2 crystals. So we are thinking about if it is reasonable to compare the spectra of MoS2 for the energy shift and further apply the energy calibration. Would you please give me suggestions? Thank you in advance. Q1. In two beam lines, for exactly the same MoS2 crystal, we got difference in XANES region. Spectrum from DESY has a weak preedge peak resolved in XANES while ERSF doesn't. And the derivative shape of the two spectra for MoS2 collected from two synchrotrons are not well overlapped. Is it acceptable? Q2. I tried to overlay the first derivative of the two spectra of MoS2. There is a energy shift at 2.5 eV from the different synchrotrons if we take the one from DESY as standard. Can I apply the energy shift at 2.5 eV for MoS2 from ERSF and then overlay the first derivative of the other NiMo samples with MoS2 to get the energy calibration? Or should I apply 2.5 eV for all the NiMo sulfided samples? Q3. Since we lost the signal for the foil reference in ERSF, we tried to put the foil in the sample position. The first derivatives of the foil spetra from time to time overlap quite well. Should we set the energy calibration at 0 according to the stable foil signal? Sorry for the long email. Thank you for the time reading it. Hopefully I made the questions understandable to you. Looking forward to your answer! Thanks. Regards, Lei Technical University of Munich

atoms tab doesnt appear on d-artemis
by Kim, Sarah 13 May '14

13 May '14

Hello, I am currently using d-artemis (on 9.18.2) and when I import a feff.inp file, the run atoms button is unavailable and there are no paths under the paths tab. I have used this feff file before on the same program without this issue. I attached a screen shot of what I am looking at. I have already uninstalled/reinstalled the program. Ive also tried using different feff files and I have the same issue. Also, this feff file works fine on the old version of artemis. Thank you, Sarah Kim Washington State University

XANES + EXAFS for light elements in diluted samples
by Marcelo Alves 11 May '14

11 May '14

Dear all, I am interested in running some measurements of XANES and EXAFS K-edge spectra of elements such as Ca and S sorbed onto commonly found oxisol minerals, i.e natural kaolinite, gibbsite, hematite, and goethite. Besides appropiate filters to attenuate the fluorescence signals that come from elements such as Al and Si, what would the other instrumental conditions (e.g detector type, photon flux, etc...) needed for getting usable spectra of those elements in diluted samples? Any suggestion on the more adequate beamline to carry out such measurements? Kind regards, Marcelo.

Atoms and Feff for CuFe2O4 structure
by Qasim Imtiaz 04 May '14

04 May '14

Dear all, I am using Atoms to calculate a Feff input file for CuFe2O4 spinel. However running Atoms/Feff results in program crash owing to 'two atoms very close together'. I modified the .cif file before importing (owing to partial occupancy issue) as following: Deleted: Fe2 Fe3+ 8 d 0.5 0.25 0.125 . 0.5 0 Modified: Cu1 Cu2+ 8 d 0.5 0.25 0.125 . 0.5 0 to Cu1 Cu2+ 8 d 0.5 0.25 0.125 . 1 0 After importing the file in Atoms, I also used different shift vectors (e.g. -0.125 -0.125 -0.125) but the issue is not resolved. Can someone help me please to solve this problem? Thanks. Best Regards Qasim
