Hello, I’m currently using Athena using the iXAFS 3.0.3 application, which is – if I’ve well understood – an old version no longer updated (http://cars9.uchicago.edu/ifeffit/Downloads http://cars9.uchicago.edu/ifeffit/Downloads). So, today I tried to install the current version by installing Demeter, following the procedure detailed at http://bruceravel.github.io/demeter/ http://bruceravel.github.io/demeter/. I’ve *carefully* installed Macports 2.3.3, i.e., installed Xcode 6.4, agreed to Xcode licence, and installed Macports for OS X 10.10 Yosemite. I runned the sudo port -v self update command Then sudo port install xorg-server demeter And port upgrade outdated to ensure everything is up to date Plus, I have XQuartz 2.7.7 installed. Here is my problem. Athena launches well from the Terminal (in home directory), I have the main window (pearl5.22), I can import data or load former athena projects etc, but there is no plot window. No error message shows up in the terminal. However I can still produce a PNG of the plot I’m desperately trying to see via Plots/Save last plot as... I’ve seen a similar thread concerning such an issue in OS X Mavericks but couldn’t solve it from what was explained there (http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2014-January/011644.html http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2014-January/011644.html). I guess the issue comes from the DISPLAY environment but I don’t have any clue to solve that. Thank you in advance for your help, I think it may be useful for other users, Kind regards, Rémi ––––––––––––––––––––––––––––––––––––––– Rémi Belissont Ph.D. Student | Université de Lorraine – Labex R21 GeoRessources CNRS-UMR 7359, Faculté des Sciences BP 70239, 54506 Vandoeuvre-lès-Nancy Cedex, France Phone +33 (0)3 83 68 47 14 Centre de Recherches Pétrographiques et Géochimiques CNRS-UMR 7358, 15 Rue Notre Dame des Pauvres BP 20, 54501 Vandeuvre-lès-Nancy Cedex, France
