PPC Macintosh version of Horae 65 on SourceForge
by Paul Fons 25 Jul '07

25 Jul '07

I have made a new Macintosh installer for the PPC version of Horae 065 available on sourceforge. It would be neat if it could be copied to the cars download list in the wiki as well. Let me know if there are any problems. It seems to work fine on my end. As there are now two versions, a PPC and an Intel version, I have included PPC in the installer name, e.g. Ifeffit-1.2.9-Mac10.4_PPC_horae65_pkg.dmg Paul p.s. perhaps we should put the Horae 065 installer for Intel on the SourceForge site as well?

[Fwd: Re: Mac intel OSX - Feff6 whereabouts]

Thanks for the advice, but sadly it didn't work. I also tried deleting the whole .horae and Perl folders and then reinstalling iXAFS, but that didn't help either. I checked the artermisrc file and it does say feff6 in the correct place, it just doesn't seem to be able to find feff6. Any more tips?

Athena 0.8.053, Artemis 0.8.010, Hephaestus 0.16
by Bruce Ravel 21 Jul '07

21 Jul '07

Hi folks, Just in time for the APS XAFS summer school, I am pleased (and relieved!) to release the latest source code for my XAS analysis programs Athena, Artemis, and Hephaestus. Here is a discussion of the new features: http://cars9.uchicago.edu/iffwiki/HoraeVersion065 Tarballs with the new source code can be found at my web site and at SourceForge. Matt and I are very close to having a new installer package for Windows. We will make an announcement when it hits SourceForge and the Ifeffit website. Hopefully packages for Mac/Motorola, Mac/Intel, and debian will be available soon. This release features LOTS of fixed bugs and user interface improvements to all three programs. The biggest new feature in Athena is the project selection dialog, which is described here: http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/import/projsel.ht… Hephaestus sports an interesting new tool for helping you select the correct fluorescence filter: http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/hephaestus.html#p… As always, let me know about any comments, suggestions, observations, or bug reports you might have. Thanks to everyone who helped with this release.

Ross, The Ifeffit mailing list is a superb resource for all your ifeffit+friends questions. http://cars9.uchicago.edu/mailman/listinfo/ifeffit/ Among the many nice things about the mailing list is that there are a number of people who, unlike me, use the Mac and will know the answer to your question. I have taken the liberty of forwarding this along to the mailing list. You should join the list so that when someone answers, you will get the mail.

I have a new Intel MacBook with OS X version 10.4.10. I installed the X11 SDK from the OS X dvd, after I install it I could install your package.

Either choice the program icon appears briefly in the dock then dissappears, this happens for all the programs. Any advice would be appreciated.

Mac intel OSX - Feff6 whereabouts
by Katy Evans 16 Jul '07

16 Jul '07

Hi, Apologies if this question has a very simple answer but I can't work it out. I installed the iXAFS package onto my new Mac (OSX 10.4.8) and almost everything works very well and it is very pleasant to use so thankyou. BUT Feff6 won't run. I can fit to existing Feff calculations but I can't make new ones, from .inp files that used to work on my other computer, or from quick first shell calculations. The message from Artemis starts 'This error is probably due to having Artemis configured incorrectly and so it does not know how to run Feff on your computer...' and goes on to say that I should check the value of the Feff executable in Preferences, and set it to Feff6. So I checked it and it was indeed Feff6. I looked for Feff6 on my computer and could only find a Feff6.atp file in the Perl directory (/Library/Perl/5.8.6/darwin-thread- multi-2level/Xray/atp) - should there be anything else? I tried typing this address into the box for the Feff executable option but this didn't help. I tried to remove everything and reinstall from the disk image but I am not sure if that was successful since I still only got the option to 'upgrade' when I clicked on the installer package. Where are all the things I need to remove if I want to get rid of the old version? Thankyou, Katy Katy Evans Dept.

Basic questions on XANES
by Ashley Harvey 14 Jul '07

14 Jul '07

Dear ifeffit users, This posting is with quite basic questions on XANES data processing. I am a somewhat new XANES experimentalist, in a group that does not typically use XANES, so I am lacking some basic knowledge. For normalization of XANES, my impression is that people generally normalize the spectra from ca. 50 eV up to 100 eV or more after the edge onset. Is there a standard acceptable normalization range for K edges? I have noticed that when I change the start of the normalization window by even a few eV, this can make substantial differences in the XANES when comparing two similar spectra (for example, change in peak and pre-edge peak intensities between XANES of one sample at two temperatures). I keep second-guessing my choice of normalization range. Second, I am also looking at the effect of the various ways to set E0. When I start with ifeffit's default (how is this determined?) and then proceed to set E0 to the zero-crossing of 2nd derivative, I'll get value X. When I change it to a set fraction of the edge step (is this legitimate?) I typically get a lower value, and then when I proceed again to set it to the 2nd derivative zero-crossing, I get a value different from the first time it was set to the zero- crossing. For example, the E0 at an Fe K edge: ifeffit default = 7128.9 eV 2nd derivative zero = 7128.8 set fraction = 7125.1 2nd derivative zero = 7125.5 The value given by the 2nd derivative zero-crossing is dependent on the previous E0 setting. I am having a hard time to move on to the actual interpretation of the data while I am still uncertain about such details. Thanks for your patience with some simple questions. Best, Ashley

xanes pyrite
by s440697＠stud.uni-goettingen.de 10 Jul '07

10 Jul '07

Hello, i have problems with feff-xanes calculations related to pyrite. I try to get the k-edge of sulfur (as absorber) in FeS2. I get the edge at ~2472 eV and i think this is wrong because i get the same energy with gypsum and i think there should be an energyshift related to 2472 eV. My proceeding is as follows: calculate the atomic positions with the asymetric unit from the http://rruff.geo.arizona.edu/AMS/amcsd.php database (Pyrite spacegroup Pa3) respectively http://rruff.geo.arizona.edu/AMS/xtal_data/CIFfiles/00596.cif with "powdercell 2.4" feffrun with the feff.inp-file like in the attachment (thanks to Josh Kas for his feff-hints) I started the feff-run on the one hand with 12 atoms (unitcell) and on the other hand with 22 atoms (14x Fe and 8x S in the cube) After this i plotted from xmu.dat the absorbtion mu (column 4) as a function of the energy (column 1). The result is in the attachment too. I don't know why i get everytime the Sulfur-k-edge at the same position (for pyrite or gypsum) respectively without energyshift related to 2472 eV. many thanks for your help :-) Ciao, Eckhard

Thanks for the help, I did a mess using the pgplot package from the distro instead using that compiled with the Ifeffit distribution. I removed that of the distro, cleaned up the installation and started again with the pgplot_install script. Everything is fine now. It took just a few minutes. The fact athena was working (I got a graphic window), while the python wrapper not, that puzzled me.

Re: [Ifeffit] RE : Ifeffit Digest, Vol 53, Issue 1

Hi Emilano, I use the python wrapper for Ifeffit on linux all the time, and also use python "for several things on the beamline". And just for the record, I do not use debian packages. Over the years, I've experienced many problems using a shared object version of PGPLOT with Ifeffit and its wrappers. These problems are why I wrote PGPLOT_Install, and why I strongly recommend following the instructions for installing Ifeffit, which includes first installing PGPLOT with the PGPLOT_Install script. They are also why I asked you to run 'ldd' on both /usr/local/bin/ifeffit and /usr/lib/python2.5/site-packages/Ifeffit/_ifeffit.so to see what libraries they load dynamically. Is there a problem with doing these steps? If so, try to find someone who can help you follow the build instructions. For 1.2.10, I will make the following changes: a) PGPLOT_Install will be altered to create libpgplot_iff.a instead of libpgplot.a, and this will be installed to /usr/local/share/ifeffit/pgplot. b) The configuration and makefiles will be altered to link against this libpgplot_iff.a, and not with libpgplot that might be installed by some other package. This will avoid the sorts of conflicts you're seeing an also eliminate the possibility of assuming that using the debian/whatever PGPLOT package will work, as it will not work for anything. It will cause some headaches for everyone using the source installations will be forced to do a COMPLETE re-install (including PGPLOT_Install). But, if someone decides to build and support a package for Ifeffit it will then have no chance of conflicting with or depending on any PGPLOT package. Cheers, --Matt
