Hello, I have followed the steps to install macports on my mac and it seems to be working. However when I went to port in demeter it start and fails rather quickly giving this error message. Error: org.macports.archivefetch for port libcxx returned: archivefetch failed for libcxx @3.7.1_0+universal What do I need to do in macports to get it to properly fetch libcxx? Thanks, Justin

Time reversibility of multiple scattering paths
by Inwood D. 18 Nov '16

18 Nov '16

Hi All, I've just been reading the paper with the following reference: Nashner, M. S.; Frenkel, A. I.; Adler, D. L.; Shapley, J. R.; Nuzzo, R. G. Structural Characterization of Carbon-Supported Platinum - Ruthenium Nanoparticles from the Molecular Cluster. J. Am. Chem. Soc. 1997, 7863, 7760-7771. In particular I was interested about the data analysis section on page 7763 (footnote 32) where the authors talk about time reversibility of multiple scattering paths. It is mentioned that the collinear DS path, in the fcc structure, (M - M(1) - M(4) - M) is time reversed, so has twice the degeneracy, but that the collinear TS path (M - M(1) - M(4) - M(1) - M) is not time reversed. Why is the DS path time reversible, but not the TS path despite the apparent 'symmetry' of the TS path? What makes a scattering path time reversible? Does time reversibility only apply to collinear paths or can it also apply to triangular paths as well? Thanks for your help, David David W Inwood PhD Researcher Chemistry University of Southampton Southampton, UK SO17 1BJ

Athena crashing with "Larch_Server not found"

Dear List, Recently installed Demeter on Ubuntu for a master's lab work at Bessy II (HZBerlin), with help from David Hughe's instructions (https://bruceravel.github.io/demeter/documents/SinglePage/demeter_nonroot.h…) When I run Athena ("dathena" in comand line) the interface window appears but command line has output: $ dathena Trying Larch server: /home/frederik/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/share/ini/larch_server.ini Trying Larch server: larch_server -p 4966 start Can't exec "larch_server": No such file or directory at /home/frederik/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Larch.pm line 66.

athena LCF issue
by fred.mosselmans＠diamond.ac.uk 08 Nov '16

08 Nov '16

Dear Bruce, I realise you may be travelling soon , This is not a very serious bug as I have work rounds. I was demonstrating linear combination fitting in Athena using the gold thiobacteria example this week. I am using 9.25 on a windows 7 computer. I read in all the data from the cynaobacteria project file I mark 5 or 6 standards In the LCF tab I use marked groups, untick the sum weights to 1 option leaving just the all weights between 0 and 1 option selected. I pick a sample spectrum eg 4.73 I select fit all combinations It rolls through them and reports the apparently correct results but an error message is reported: Redundant argument in sprint at C:/... /AppData/Roaming/DemeterPerl/perl/site/lib/Demeter/UI/Athena/LCF.prm line 780, <F> line 122 Clicking any of the answers in the combinatorics tab brings up this error again. If I do a fit of lot of spectra using the same set of standards, I get a similar error message except this time it is line 906 and some of the combined spectra don't plot properly until you refit them as a single spectra in the standards tab I attach a log file but not a project as I assume you can find that on github!

Larch mback error report
by Sean Fackler 01 Nov '16

01 Nov '16

Dear Larch developers (Matt), I believe I found an error in the mback function where I get a NameError saying the name ‘f1_chantler’ is not defined. I found that simply adding f1_chantler to the larch_plugins.xray import section in mback.py fixes the problem. I have included the modified mback.py code, my input data (SigScan226827.txt), project code (mback_test.py), and the error I received (mback_error.txt). I am running python 2.7 with anaconda as my manager, macOS Sierra v10.12, on a mid-2015 15” MacBook pro. I hope this report is correct and helpful.

Athena and "norm" file groups
by Mike Massey 19 Oct '16

19 Oct '16

Hi everyone, Apologies if this has been covered before, I'm just getting around to upgrading to Demeter. I have a bunch of old project files with a mishmash of data from different sources, and I'm having trouble getting them to work fully with the new software. Any group with a data type of "xmu" (energy space) seems to work as expected, but any group with a data type of "norm" (normalized data) doesn't seem to work properly when it comes to spline or post-edge background subtraction (which is handy if I want to do LCF, for example). Is this a bug or a feature? Has anybody yet developed a workaround? Any thoughts or advice would be greatly appreciated. The ultimate workaround is to use different data, but I'd like to use existing projects if possible (saves a lot of time and brain damage). Cheers, and thanks! Mike

General question
by Dimitar Popmintchev 14 Oct '16

14 Oct '16

Hi All, I would like to ask, after a fit (in Artemis) which column in the output file gives the uncertainty for peaks position dR (R+/-dR i.e. 3+/-0.02 Angstroms) ? Is there additional information that could be extracted from wavelet transform ? Thank you. Dimitar

Artemis crash on import
by George Sterbinsky 13 Oct '16

13 Oct '16

Hello, I am using Demeter on Mac OS X 10.11.6. I recently updated Demeter to version 0.9.25 using the command "sudo port upgrade demeter". In Artemis, choosing the menu item "open project or data" causes Artemis to crash. I've pasted the information printed to the terminal below. This includes everything printed to the terminal from the point at which Artemis was started. Please let me know if any additional information would help in resolving this issue.
