Hi All, I am writing to inquire if Demeter(athena, artemis) works on a 64-bit windows 8 system. I was trying to install Demeter 0.9.20 (downloaded from http://bruceravel.github.io/demeter/)on my 64-bit windows 8 laptop. It seems install well, at least there were no problems coming out during the installation. However, when I opened Athena, and imported data (an EXAFS data file end with .dat), there was no graphic window and no data was imported into Arthena, which stopped me proceeding. I had similar problems when I tried to install the Updater package (version 0.9.18.2) after the 0.9.13 Installer package was installed. Has anyone known if this problem was caused by the incompatibility between Demeter and Windows 8, or because I didn't install any supported package? Or how can I resolve this issue? I also tried to install the source code of demeter (version 0.9.20) following the instructions on http://bruceravel.github.io/demeter/pods/installation.pod.html. All procedures (step 1 to 4 in the section 'BUILD DEMETER AND ITS DEPENDENCIES') went smoothly on my Ubuntu 14.04. When it was done, I typed 'athena' or 'artemis' in the terminal under the demeter directory and athena or artemis were launched. But the graphic interface is still PGPLOT, rather than GNUPLOT, although I have installed GNUPLOT before I built demeter. Besides that, the data column window opened through 'open files' cannot be imported, as there is no 'OK' button in the bottom left. Also, the athena version shown is 0.8.061, rather than 0.9.20 which is the version number of demeter I built. I was really confused about these working issues, stopping me at the very beginning of data processing. I'd appreciate a lot if anyone could let me know how to solve the above problems. Does anyone else have similar issues? I look forward to hearing from you soon. All the best, Yanyun Hu PhD student in Physics, University of Toronto
