problem running (D)Artemis on non-unicode machine
by Andrei Shiryaev 09 Dec '13

09 Dec '13

Dear colleagues, Again I have problems running (D)Artemis on two Win7 and on Win XP machines with non-unicode names. I've raised the issue in September and Matt Newville suggested some recipe (see IFEFFIT mailing list on Sept 6). The suggested solution was the following: ======= Edit the file C:/strawberry/perl/site/lib/Demeter/UI/Artemis.pm so that, near the top it reads: use Archive::Zip qw( :ERROR_CODES :CONSTANTS ); $Archive::Zip::UNICODE = 1; ======= The solution was great in the sense that DEMETER at least starts (it was not the case before). However, when I try to fit anything imported from old or new Athena (importing old style Artemis project does not work, this was apparently already reported to the list) I am getting the following error message (also see attached screenshot): ======= error writing zip-style project at C:/strawberry/perl/site/lib/Demeter/UI/Artemis/Project.pm line 104 Demeter::UI::Artemis::Project::save_project('HASH(0xaf38efc)', C:/Documents and setting/ NON-UNICODE NAME.......... ========== I would be grateful if an idea how to solve this obstacle. All the best, Andrei Shiryaev PS In the example above DArtemis is installed on D:, but standard installation on C: gives exactly the same result.

Re: [Ifeffit] fitting a specific k range
by fred.mosselmans＠diamond.ac.uk 06 Dec '13

What I find reassuring about Bruce's warnings is they allow you to think properly about what you are doing. Fortunately, unlike Chris, I am not of a size where I have to worry about falling down rabbit holes, unless American rabbits are much bigger than English ones. I would commend Matt's original question as it opened a debate with 3 of the mainstays of the list. That may not have been the intention but it makes interesting reading for us mailing list voyeurs.

fitting a specific k range
by Matt Frith 05 Dec '13

05 Dec '13

Dear All, I need some help in fitting an amorphous iron oxyhydoxide sample. I am having difficulty producing a good fit, particularly in the k=4-6 range. Fitting this region well is very important for me, because if I add another metal(+3 oxidation state) into my system, this is where I observe the most quantifiable changes (The shoulder @ 5 A^-1 and the min @ 5.6 A^-1). Thus far I have been unable to fit the shoulder well enough to make meaningful comparisons. I have been fitting in kq with kmin=2.566 And kmax=10.877, and Rmin=1 and Rmax=3.5, and using the goethite O1.1, Fe.1, and Fe.3 paths. Attached is an Artemis file (P41_006_merge_norm_TRANS.fpj) for an amorphous Fe oxyhydroxide sample (Fe only, no other metals). The data was collected at the Fe K-edge. *Is there a way to fit just this region (k~4-6 range) in k? If so what is the best method for doing this? If not, does anyone have suggestions as to how I can improve my fitting? Should I fit the data in k since the shoulder is less evident in kq?* Thank you for your time. Sincerely, Matt Frith

EXAFS spectra of uranyl standards
by Kate Tucker 02 Dec '13

02 Dec '13

Hi all, I was wondering if anyone has recorded an L3 edge for a single phase UO2Cl2 solid or solution, and a K edge for ZrCl4 and ZrO(NO3)2 solid or solution? I have already obtained my L3 and K edge data for the uranyl and zirconium containing systems, respectively. However, it has now become apparent that I may have something different going on to what was initially thought, so would really appreciate these spectra for use as standards. Many thanks, Kate

dartemis crash
by René Genz 24 Nov '13

24 Nov '13

Hi Bruce, hi Matt, the other day a colleague encountered a problem. He measured a ZnO standard. I have the ZnO.fpj project file and can share the data. It is about 1.2 MB in size though. Shall I upload it to a public file hoster or sent it to your email account? At first I thought this is a problem with my installation steps on Fedora 18 x86_64, but I could reproduce the problem with Ubuntu 12.04 i686. The line numbers match, so I will post only the output from dartemis on Ubuntu. Note: this file was created with the Windows version of Demeter on Windows 7 Enterprise 32bit (running on Fedora 18 x86_64 as VirtualBox 4.2.18 virtual machine). Demeter crashes in the Windows version as well using the steps below. steps to reproduce: * start dartemis from a terminal * open project file in dartemis through 'Artemis [EXAFS data analysis]' window: File -- open project * in the 'Artemis [Plot]' window click on [R] button * in 'Artemis [Data] ZnO' window click on the bull's eye sign to the right of rmax window * wait about 10 seconds; dartemis will crash with the below error message ### Ubuntu 12.04 i686 test@test2:~$ dartemis Attribute (bft_rmax) does not pass the type constraint because: Num is not larger than 0 at accessor Demeter::Data::bft_rmax (defined at /home/test/perl5/lib/perl5/i686-linux-gnu-thread-multi-64int/Demeter/Data.pm line 406) line 7.

Fwd: problem compiling ifeffit
by Bruce Ravel 10 Nov '13

10 Nov '13

Rene, Support for the software is done via the Ifeffit Mailing List. This and all other questions should be asked in that forum. http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit please note that I am CCing my answer to the mailing list. All follow-up discussion should be on the mailing list rather than by responding to me directly. Regarding the problem with png files and PGPLOT, the solution of installing libpng12-devel is the much better solution. Regarding the problem compiling the file decod.f, I am going to blame Matt for that one. It seems he made a change to that file in August of 2012 (which is more recently than the last time I did a "git pull" on ifeffit!) Pulling and attempting to rebuild, I get the same result. Fixing the problem required editing the file encod.h to define the missing symbol "jtait". I just forked ifeffit, fixed the problem, and sent Matt a pull request. Here it is: https://github.com/newville/ifeffit/pull/4 If you follow the little link that says "97f6458", you'll see the diff. If you make the edit yourself, you should be able to finish compilation. Or wait for Matt to merge the pull request, do a git pull, then finish building. Regards, B -------- Original Message -------- Subject: problem compiling ifeffit Date: Thu, 31 Oct 2013 17:36:24 +0100 From: René Genz <liebundartig(a)freenet.de> To: <bravel(a)bnl.gov> Dear Mr. Ravel, today I tried to install the latest version of Demeter on Fedora 18 x86_64 following the instructions: http://bruceravel.github.io/demeter/pods/installation.pod.html In the past I could install ifeffit on Fedora 16 x86_64. But now I need your help. I encountered a problem in compiling ifeffit. This problem is reproducible on Ubuntu 12.04 i686. Furthermore, there are two minor things that I would like to mention as well: - PGPLOT_install does not set return code, if PGPLOT was not properly installed - ./configure of ifeffit echos the following line and continues without a problem "./configure: line 3355: #include: command not found" Details about the problem follow: I used the default installation selection for Fedora (Gnome Desktop). After installation I executed the following commands $ sudo yum install -y perl gnuplot gcc gcc-gfortran libX11-devel ncurses ncurses-devel libpng libpng-devel giflib wxGTK-devel git $ cd $ git clone https://github.com/newville/ifeffit.git $ cd ifeffit $ sudo ./PGPLOT_install The compilation started by the script fails. The attached file Demeter__F20__x86-64__PGPLOT_install.txt shows the last part of the output. I could work around this problem in two ways. Either a) sudo ./PGPLOT_install --no-png OR b) sudo yum install libpng12-devel ; sudo ./PGPLOT_install I used 'a)' and PGPLOT could be installed by the script. So I continued with the compilation of ifeffit. This is where I encountered a problem that I could not solve. $ ./configure was OK, just one line catched my attention "./configure: line 3355: #include: command not found" $ make The full output is in Demeter__F20_x86-64__ifeffit-configure-make.txt Here is the last part of the output: gfortran -g -O2 -fPIC -c iff_sync.f gfortran -g -O2 -fPIC -c decod.f decod.f:191.26: elseif (ic.eq.jtait) then 1 Error: Symbol 'jtait' at (1) has no IMPLICIT type make[3]: *** [decod.o] Error 1 make[3]: Leaving directory `/home/user/ifeffit/src/lib' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/user/ifeffit/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/user/ifeffit' make: *** [all-recursive-am] Error 2 The error message refers to ./src/lib/decod.f I do not know how to solve this problem. Do you have a suggestions how to solve this? -- Kind regards, René

Re: [Ifeffit] error in ATOMS
by Ravel, Bruce 09 Nov '13

Julius, I am CCing my response to the Ifeffit mailing list (http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit) which is the appropriate venue for questions about the software. The problem you report is surprising to me and certainly not something I see normally. I will need to see an example on my own computer. If you could post an example of crystal data that triggers this, that would help. When you send this to the mailing list, also let us know what version of the software you are using.

I do not know how to fix that or go around it. Hopefully you can help. Thank you, Bruce. Julius
