Re: [Ifeffit] New Demeter Win7 install (?) problems

Hi i dont know if this is relevant but the problem sounds similar to one i had at Diamond with Demeter that was covered on the list about six weeks ago. that was with XP hence i am not certain it's relevant. what was missing is the demeter folder for the log file to write to in the %appdata% folder. creating (for each user) a demeter folder in their %appdata% enables the log file to be written and the program to run. for my windows 7 home pc this appears to be uesername/appdata/roaming cheers Fred -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.

New Demeter Win7 install (?) problems
by Latta, Drew E. 23 Apr '12

23 Apr '12

Bruce: I am having issues with getting the new Demeter release for Windows to work on my Win7 machine. The install program runs just fine and drops shortcuts to Artemis, Athena, Atoms, and Hephaestus on my desktop. However, when I click on the shortcuts to run these programs I get a very quick flash of a command line window saying something to the effect of: "The system cannot find the path specified." The shortcuts on the desktop point to, for example: "C:\demeter\perl\site\bin\dathena.bat" and there are batch files in the specified location with what appears to be useful text in them. Note that I get the same issue if I un-install and re-install to the default C:\strawberry directory. Running the batch files from their actual directory does the same thing, suggesting to me that the problem lies somewhere deeper than I have the wherewithal to de-bug. Did I miss a crucial step somewhere? Cheers, Drew Latta ----------------------------------- Drew E.

Demeter
by Vanamee, Eva 23 Apr '12

23 Apr '12

Bruce, Demeter is a wonderful program and the GUI is beautiful! I am old enough to remember the time when we were doing things by commands. I am also rusty and have not done EXAFS in years. Is there an easy way to convert a PDB file into a feff.inp file? I am working on a protein with a [4Fe-4S] cluster. I have generated a PDB file with just the iron-sulfur cluster in it. File attached. I am having a hard time with ATOMS, even when I use a single Fe atom placed at the origin. Thanks, - Eva

Yvonne, There are a number of problems with your project file. Setting aside the inherent difficulty in measuring the Br K edge of a gold-bromine complex (the Au L2 edge is only 8.2 inverse Angstroms above the Br K edge), you have made a few mistakes in your feff input data. First, it would seem that you started from a feff.inp file you prepared for use with Feff8 or Feff9. The "XANES" keyword makes Feff6 (the version bundled with Ifeffit and Demeter) unhappy. I believe this is the proximate cause of the error message you initially reported last week. Unfortunately, Artemis does not provide a useful warning that Feff stopped without running properly to completion when it encountered the "XANES" keyword. That needs to be fixed. Thanks for bringing that to my attention. Second, you had an RMAX value in the Feff input data of 80. That's not a problem per se, but it does make Artemis issue a warning message since it's an oddly large value. Third, it seems that you started with Feff input data for the Au L3 edge then edited it to make one of the Br atoms the absorber. You did this 75% correctly. You did the right thing with the potentials list and the ipot values, but you forgot to change the HOLE value from 4 to 1. 4 is the value for the L3 edge, 1 is the value for the K edge. That is a common mistake -- indeed one that I make regularly -- that has come up on the list in the past. It tends to result in large E0 values since the phase of scattering an L3 photoelectron is so different from the K. In the end, I couldn't make much out of your fit, however. The data range is so limited that you have very little information to work with. And I suspect that the presence of the L2 edge is dominating the determination of the background function. I bet that the peak at 1 Angstrom is a background removal artifact. It is hard for me to believe that a gold scatterer at almost 2.5 Ang would make a peak at only 1 Ang in the Fourier transform. You might try restricting the range of the spline in Athena to something that does not include any of the Au L2 edge step. Even so, I am not so optimistic about being able to interpret these data. (Although, as part of multiple data set fit they may prove useful....) In any case, by making those fixes to the feff input data and re-clicking the run Feff button, I was able to make the program behave correctly.

first "official" relezse of my new software
by Bruce Ravel 22 Apr '12

22 Apr '12

Hi everyone, Today I am announcing my first official release of my latest version of my XAS data processing and analysis software. The package is called Demeter, the version number is 0.9.9, and it includes new versions of Athena, Artemis, and Hephaestus. In many ways, these are much like the versions of the software that have been in use for almost a decade. In many ways, however, they offer important improvements, including better plotting, prettier GUIs, and lots of new analysis features. For those using Windows, you can download the installer package from https://github.com/bruceravel/demeter/downloads For those using Linux, installation instructions can be found at http://bruceravel.github.com/demeter/pods/installation.pod.html I am hoping that installer packages for the Mac and for specific Linux distributions will become available in the coming months. The Demeter versions of the programs can coexist on a computer with the old versions. New Athena and old Athena peacefully coexist, indeed, they use the same project file format. The project file format for new Artemis is different, however new Artemis can import project files from old Artemis. I am no longer developing the old versions. I will no longer fix bugs or add new features to the old versions. All of my future develop efforts will be devoted to the new versions. Here are some useful links: Demeter's github page: https://github.com/bruceravel/demeter Demeter documentation: http://bruceravel.github.com/demeter/ Reporting bugs: http://bruceravel.github.com/demeter/pods/bugs.pod.html Artemis instruction videos: http://vimeo.com/channels/exafs It has been a joy to develop and support my software over the years. My interactions with the kind, engaged people in the community of Ifeffit users have been among the high points of my career. I hope that you enjoy my new software as much as I enjoyed writing it.

Column label issue
by Vanamee, Eva 20 Apr '12

Hi Bruce, Somehow my earlier email bounced. I did try Erik's suggestion and renamed the columns with shorter names. It all works fine now after giving short Ch1, Ch2,... names for the columns. I am onto ARTEMIS and new issues. more soon....

Path file does not exist
by Yvonne Grunder 20 Apr '12

20 Apr '12

Hallo, I have currently a problem with Artemis to fit my data. First, I import the paths from the Feff calculation and define my fitting parameters. Then I can run the fit exactly one time. If I try to fit the data a second time, I get the following error message: PATH: Au ( 9999 1 2.470 ---- @ Au @ 2 2 single scattering) The path file does not exist (perhaps the Feff calculation was not run). (and similar for all paths included...). Did anybody encounter a similar problem (I already reinstalled Demeter)?
