HI, all

I am a beginner user of Athena and Artemis and ATOMS. It is very nice to find Athena and Artemis manuals, they are helpful:

1. Do you have FeS2 and other Fe mineral EXAFS data as described in your manual, and associated data files, so that I can practice following your manual.
2. When I ran ATOMS standing alone, to input the crystal structure data that have more than 7 atom sites. I could not add a site by clicking "Add a Site" button, is there a problem for ATOMS, or it may be related to our SRNL security system.
3. Currently, my project is to study U adsorption to natural organic matter and minerals (e.g., goethite) surfaces, do you have any template files available for calculating FEFF or if you can instruct me where I can start for such systems: for example, uranyl-C or uranyl-goethite surfaces.
4. How to define the fitting models and GDS parameters for such U systems.  

Thanks you so much for your help.
