Problems with EXAFS Fitting of Metalloprotein Zinc Samples
by Carolyn Carr 11 Nov '15

11 Nov '15

Hi, I have a general question rather than specific. I have only ever fit XAS data on metalloproteins and one feature that I see is that when fitting Zinc samples in R-space there is no local minima. For Cobalt and Nickel samples I typically get one or a few fits that are obviously significantly better in R-factor (with reasonable distances, sigma^2, etc) but for Zinc this is not the case. I can get many good fits and Zinc likes to increase the coordination up to 8 for all data sets I have ever fit, although there is obviously no physical basis in this. This is true of not just my own proteins but Zinc samples made by collaborators, and after looking through previous group members fit tables, they had similar issues. My understanding is that one of the benefits of fitting in R-space is that there is a local minima, whereas in k-space there are many minima. I was wondering if there was a physical basis for this feature in Zinc samples, or if perhaps my group is not aware of some experimental setup that we should be doing for Zinc that would resolve this problem. Thank you for any help regarding this matter, Carolyn Carr

Problems with EXAFS Fitting of Metalloprotein Zinc Samples

Hi Robert, Thanks for your reply. We have done this with standard samples and we see the same thing. And of course, we can tell qualitatively from the XANES that our sample is not 8 coordinate, and not even 6 coordinate. We have never tried changing the temperature but we can try this the next time we go to SSRL. We actually do fit multiple scattering features as imidazoles which is one of the things we consider as a strength of Artemis for our basic needs. This is part of why we think this is strange, because putting 8 imidazoles around a zinc seems kind of silly but it likes it. 5 imidazoles and 3 sulfurs and I have an R-factor of 0.2% every time. If there is non standard multiple scattering that occurs in multiple unrelated proteins from different organisms then we would have no idea what this could be. Thanks for your comments! Carolyn Carr

I have downloaded the zip-file containing the example files and extracted them into other subfolders (i.e. C:\Users\Marcelo\Documents\1.Athena Calibração e Alinhamento\Examples\Fe foil). I think that this was my error. When I use C:\Fe foil the file was opened in Athena without any issue.

Dear Matt and Bruce, The problem is not with loading the files from the project, but instead to "load the loaded" files to the Data Summation. For example try to import all groups from the project of the example "Cu Metal" ( I will also attach it). Now go to data summation tab, in the components selection I'm able to select all groups except the first. (Shown in picture 1 attached). Now try to delete all groups and try to import groups from another project, let's say "Methylin" (attached). Now the groups avaiable for data summation work are still the previous ones (shown in picture 2). It seems that the data summation tab is not reading actively the groups loaded! I hope the situation it's clear now. Meanwhile I would also like to ask if there is a way to export the worked data ( for example, resulting from merges or sums) to new .dat files (in x-y coordinates).

Opening "older" data files in the latest Athena version
by Marcelo Eduardo Alves 09 Nov '15

09 Nov '15

I have downloaded the worked examples available at https://github.com/bruceravel/XAS-Education However, I am not being able to open them in the latest Athena version (0.9.24) (e.g., Fe.060 of Fe foil folder). Could those files be opened in the last Athena version? Thank you. Marcelo.

Dear all, I am using the latest version of Demeter (0.9.24) and I have downloaded the data files available at https://github.com/bruceravel/XAS-Education. However, I am not being able to open the example files in Athena (e.g., Fe.060 of Fe foil folder). Please, would it be possible to open those example files in the latest Athena version. Thank you.

Dear Bruce, I try to instal Demeter on a Mac running El Capitan. I carefully followed the procedure (installation of Xcode and Macports), and I type the command: sudo port install xorg-server demeter in a terminal window. Unfortunately, after about 30 seconds, I am stuck with the following message: ---> Computing dependencies for xorg-server Would you have any suggestion?
