I have used the binary installer once on a OS 10.1 system. It worked for me (after following the simple included instructions, of course) and plotting with Aquaterm did work. I haven't tried 10.2. I know the Mac binary installer does not include athena, artemis, or tkatoms. I believe it only provides the command-line ifeffit. I'm not sure I can answer many other questions about it. I don't know enough about it or 10.2 v. 10.1 issues to know how well it would work with 10.2. If the aquaterm/pgplot demos don't work, I'd guess it's a more serious problem and that the binary installer may not work. Is the Fink / X-Windows / PGPLOT installation procedure too big of a hassle? I know that can work, and that athena will work too. I also believe that the instructions are simpler for 10.2 than 10.1 (especially with respect to getting perl/Tk to work), but haven't tried this myself. I'm copying this message to the ifeffit mailing list, hoping that someone else may have better answers to these questions. How necessary is a complete binary installer for Mac OSX? Thanks, --Matt

Hello, I just wanted to echo Scott's sentiments. If someone has the time and energy to create for the Mac an executable version of the Artemis/Athena/IFEFFIT programs (and keep them updated), I'd also be very grateful. Being unfamiliar with Unix, I experienced the same problems as Scott in trying to get the programs up and running on my Mac. So, I bought a PC laptop specifically for doing data analysis with these very nice programs.

a limitation of Athena, Artemis, and Ifeffit
by Bruce Ravel 17 Jun '03

17 Jun '03

Hi folks, An irritating limitation of the codes was just brought to my attention. My colleague here at NRL had his data file in a deeply nested folder and each folder name was long and descriptive. The end result was that the fully resolved file names (i.e. path and name) was many dozens of characters. When he tried to import these data into Athena, Athena failed silently. That is, Athena failed to import the data and failed to report a reason why. The reason is that there is, in ifeffit, a limit to the total number of characters for the fully resolved filename. My colleague, with his long, descriptive folder names, had exceeded this limit. In that situation, the current version of Athena (and Artemis, as well) fails silently. In the next versions of the codes, they will issue a warning if your fully resolved filename is too long. For the moment, however, the best I can do is to make you all aware of the problem and to suggest either short folder names or placing your data high up in the file tree.

athena 0.8.020 and artemis 0.6.005
by Bruce Ravel 16 Jun '03

16 Jun '03

Hi folks, Just in time for the XAFS conference, I am announcing new releases of Athena and Artemis. There are not many major new features this time, but there is a long list of bug fixes and usability enhancements. If you have not yet upgraded to Ifeffit 1.2.1, you should do so, then download the latest versions of my codes. As always, new source code tarballs and windows executables can be found on my downloads page. For those Windows users new to the mailing list, I'll explain how to install the new executables. It's quite simple. Grab the .exe files from my downloads page and drop them in the C:\Program Files\Ifeffit\ folder on top of the old versions. If you installed to some other location, then drop th new executables there. Doing this is enough to leave the desktop and Start Menu icons functional. The one major new feature in Artemis is the ability to set restraints on your parameters. It's as simple as setting a math expression on the "Guess. Def, Set" page and flagging the parameter as a restraint. The restraint defined this way will then be used in the fit. If you are interested in using restraints, you should read the following: http://cars9.uchicago.edu/ifeffit/refman/node55.html http://cars9.uchicago.edu/xafs/Advanced_Methods/BNLworkshop2001/newville.pdf There is an example project file using a restraint in the source code tarball which follows very closely the restraints example from the ifeffit source code tarball. There really are a lot of improvements this time around and it is well worth updating. Check out the change logs on my web site for all the details. The acknowledgment list is a long one this time. Among those with helpful bug reports and good suggestions: Scott Calvin, Vince Harris, Dale Brewe, Adam Webb, Mark Jensen, Paul Fons, and Grazia Proietti. Thanks to all of you. The award for the loopiest suggestion which I had no good reason to refuse goes to Mark Bondin, who wants to use Athena for background removal and Xfit for data analysis! B P.S. There are a few of you who have expressed an interest in using Artemis to analyze your DAFS data. It was pointed out to me that I had forgotten to include the dphase path parameter in Artemis. That has been fixed, although the dphase parameter is hidden along with the k_array, amp_array, and phase_array path parameters. If you want to use dphase or any of the other three "hidden" parameters, go to the Paths menu and click on the button at the bottom of the menu that reads "Extended path parameters". When you click it on, text boxes for dphase and the _array path parameters will be displayed on the paths page in Artemis. P.P.S. I am giving a poster about Athena and Artemis at the XAFS conference. My time is Wednesday during the 16.15 to 17.45 session. If you'll be at the conference, stop by and say hi. I'd enjoy meeting those of you I don't already know and would enjoy catching up with those I do. -- Bruce Ravel ----------------------------------- ravel(a)phys.washington.edu Code 6134, Building 3, Room 222 Naval Research Laboratory phone: (1) 202 767 5947 Washington DC 20375, USA fax: (1) 202 767 1697 NRL Synchrotron Radiation Consortium (NRL-SRC) Beamlines X11a, X11b, X23b, X24c, U4b National Synchrotron Light Source Brookhaven National Laboratory, Upton, NY 11973 My homepage: http://feff.phys.washington.edu/~ravel EXAFS software: http://feff.phys.washington.edu/~ravel/software/exafs/

XAFS 12
by Matt Newville 07 Jun '03

07 Jun '03

Hi Everyone, Many people on this list will be at the upcoming XAFS 12 conference, and have probably seen the notice for the microsymposium on XAFS analysis programs. Bruce will talk about the 'Ravelware', I'll talk about Ifeffit etal, and several real luminaries in the field will talk about XAFS and XANES analysis. The conference is a great chance for many informal discussions about the ifeffit programs. At this point, there are many possible directions for development and improvement and I (and I assume Bruce and Sam) would love to hear feedback on what the priorities for new functionality and development should be. It might be good to set aside a lunch time (or beer-time?) to talk about development priorities. I'd tenatively pick Thursday lunch (after the analysis symposium and most posters/talks to be able to learn some things from the conference), but maybe we can finalize the time and place at the Tuesday evening analysis symposium. A few possible topics of discussion are 'Installation on MacOS X' and 'Getting GUIs that run Feff6', but there may be other issues. If you're interested, please feel free to join the discussion, and see you in Malmo! --Matt
