Peak locations for Phosphorus in Carbon K-edge
by Kenneth Latham 28 Aug '17

28 Aug '17

Dear All, I have analysed some phosphoric acid activated carbons via NEXAFS and was wondering if anyone had come across any references or knew where the transition/peak for the C-O-P or C-P-O bonding arrangement occurs in the carbon K-edge region. The samples I am examining are a series at different heat treatment steps and lose a lot of oxygen functionality, so finding where C-O-P or C-P-O transitions occur would be very useful in understanding the chemical transitions that are occurring. Regards, Ken

Hi Hiroyuki, I done a small interface to Larch to work with a lot of files http://soonready.github.io/PrestoPronto/ It is not nice as Athena and it has not all its possibility but if you are used to Athena you should not get lost (the name of parameter is the same ). It is not fast how it should be but give a try, maybe could be useful Carmelo On Thu, Aug 17, 2017 at 7:00 PM, <ifeffit-request(a)millenia.cars.aps.anl.gov> wrote: > Send Ifeffit mailing list submissions to > ifeffit(a)millenia.cars.aps.anl.gov > > To subscribe or unsubscribe via the World Wide Web, visit > http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit > or, via email, send a message with subject or body 'help' to > ifeffit-request(a)millenia.cars.aps.anl.gov > > You can reach the person managing the list at > ifeffit-owner(a)millenia.cars.aps.anl.gov > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Ifeffit digest..." > > > Today's Topics: > > 1.

How to use Larch as backend for Athena and Artemis on Windows
by ASAKURA, Hiroyuki 18 Aug '17

18 Aug '17

Dear all, I would like to use the latest Larch as backend for Athena and Artemis on Windows to handle hundreds of XAS data (, hopefully). But, I'm stuck. I would appreciate any comments and suggestions. Matt announced it is now possible on this list, but I still cannot do it on Windows.

How to use Larch as backend for Athena and Artemis on Mac (Re: Ifeffit Digest, Vol 174, Issue 8)
by Luke Higgins 17 Aug '17

17 Aug '17

Dear All, Following the excellent guide that Hiroyuki & Bruce gave for running larch on Demeter on Windows (Ifeffit Digest, Vol 174, Issue 8). The following steps worked for me to run larch/Demeter on MacOS (Sierra 10.12.6). 1) Install Demeter using the advice from: https://bruceravel.github.io/demeter/documents/SinglePage/macinstallation.h… 2) Installed Anaconda and larch using the following guide: http://cars.uchicago.edu/xraylarch/installation/index.html (Python & larch from source is fine: but then use Hiroyuki’s step 3&4 advice [attached below]) 3) In a new terminal window check larch by: larch --version You should see "larch command-line version 0.2". 4) Running larch and Demeter, run in a new terminal window: larch --port=4966 –rc 5) Open Demeter.pm in a text editor (which for me was buried in: /opt/local/lib/perl5/site_perl/5.24/darwin-thread-multi-2level/Demeter.pm) and change line 44 to: $ENV{DEMETER_BACKEND} ||= 'larch'; 6) This has changed both Athena and Artemis to using larch – haven’t fully tested yet, but looks good. Best Wishes, Luke (from Hhiroyuki, installing python and larch from source files:) 3. Install unofficial Numpy and Scipy, Python libraries 3-1. Download numpy‑1.13.1+mkl‑cp36‑cp36m‑win_amd64.whl and scipy‑0.19.1‑cp36‑cp36m‑win_amd64.whl via http://www.lfd.uci.edu/~gohlke/pythonlibs/ 3-2. pip install numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl 3-3. pip install scipy‑0.19.1‑cp36‑cp36m‑win_amd64.whl 4. Install Larch and its dependencies 4-1. Start a command prompt 4-2. git clone https://github.com/xraypy/xraylarch.git 4-3. cd xraylarch 4-4. pip install lmfit 4-5. pip install h5py 4-6. pip install pillow 4-7. pip install requests 4-8. pip install sqlalchemy 4-9. pip install matplotlib 4-10. pip install pypiwin32 4-11. pip install wxpython 4-12. pip install wxmplot 4-13. pip install wxutils 4-14. python setup.py install 4-15. larch --version 4-16. You will see "larch command-line version 0.2". Note: I installed Larch dependencies except for pyFAI, CifFile, fabio, tomopy, scikit-image.

Artemis can't open project file and crashes

Demeter on Windows with Inkscape (and possibly other programs)
by Bruce Ravel 10 Aug '17

10 Aug '17

Windows users: I got an interesting bug report today from a fellow who develops a popular open source program for vector graphics editing (Inkscape). Apparently, there is a problem in Demeter's installer that has an impact on the ability of that program (and possibly others) in accessing system font files. The issue with Inkscape is described here: https://github.com/bruceravel/demeter/issues/51 I mention this here on the mailing list in an effort to help the folks who maintain Inkscape. If you use Demeter and Inkscape on your Windows machine, there is a problem and it is my fault :( The simplest solution is to uninstall Demeter, then continue using Inkscape. If that's not true or if someone needs a better solution right now, post here and I will help you work out a solution. I think the real fix to the problem is simple and I will work on a new installer this month.

Athena Crashing on Mac
by Daniel Austin Sheffield Uni 04 Aug '17

04 Aug '17

Hi, I emailed relatively recently about Artemis crashing on my MacBook Pro. This is the email i sent: 'I was using Artemis on Mac and it crashed. Now when i try to reopen Artemis it attempts restore what i was doing from an autosave file but it becomes unresponsive and is just stuck on the screen posted below. Does anyone know how i can fix it? Do i have to uninstall and then reinstall the software? i have left it running for over an hour but it still hasn’t worked. Thanks for any help’ Now the exact same thing is occurring with Athena. One of the replies from the previous email instructed me to remove parts of the programme code. I did so an Artemis worked perfectly after, i just needed to save often. The full email that instructed me on this can be found below: Hi Daniel, I had a similar issue, but my solution hasn’t been put up yet on the list: With respect to the error that Katherine Davies reported (02/16/2016; RE: [Ifeffit] problem with Artemis crashing on mac), I came across the same problem when running Artemis on Mac. I believe this issue is caused by a piece of code found in “artemis.pm” (Demeter/UI/artemis.pm) line 512-521: 512 sub process_argv { 513 my ($app, @args) = @_; 514 if (Demeter->co->default("artemis", "autosave") and autosave_exists()) { 515 import_autosave(); 516 } elsif ($args[0]) { # and -e $args[0]) { 517 my $file = File::Spec->rel2abs( $args[0] ); 518 read_project(\%frames, $file) if Demeter->is_zipproj($file, 0, 'fpj'); 519 }; 520 }; I think the error is due to not shutting down the program correctly causing this code to fail. A fix is to comment out lines 514-516 & 519, save the file and reboot Artemis (to edit artemis.pm you will need to make the file writable)– thus getting you past startup and allowing you to turn off the autosave settings from within Artemis as suggested. Put the code back as it was after you have finished. Hope this helps. Best, Luke Higgins I tried searching for similar code in the Athena programme but couldn’t find it. Does anyone have a similar solution, or any solution, to this problem? Thank you so much

Hi, I was using Artemis on Mac and it crashed. Now when i try to reopen Artemis it attempts restore what i was doing from an autosave file but it becomes unresponsive and is just stuck on the screen posted below. Does anyone know how i can fix it? Do i have to uninstall and then reinstall the software? i have left it running for over an hour but it still hasn’t worked. Thanks for any help, Daniel

working at the lanthanide K-edges: question about amplitude reduction factors
by Bone, Sharon Elizabeth 28 Jul '17

Hello- I recently collected some Nd K-edge EXAFS at APS (~43 KeV). I've started fitting the data and am looking for S02 values in the literature to compare to my own (especially since my fitted S02 values- to two Nd reference materials for which I know coordination numbers- are outside of the typical range of 0.7 - 1), but I haven't found any reported. Has anyone worked at the lanthanide K-edges? Could you point me to a reference for S02? Thanks! Sharon
