Dear Patrick: The Artemis interface is designed to put the details of the workings of FEFF "under the hood", so to speak. If you really want to use the FEFF6 program on its own, you should read the the FEFF documentation: http://leonardo.phys.washington.edu/feff/ The version os FEFF6 that comes with the Ifeffit source is not exactly the one available on the FEFF page, some of the functions (specifically, printing of some kinds of output files) have been disabled because the whole idea is that Artemis and Ifeffit handle these functions at a higher level in the programs suite structure. If you want to see the weighted sum of the paths you need to probably add the individual paths somehow (I am not sure if there is an option in Artemis to do this directly or whether you will need to export the paths and then sum them back up in Athena).

Hi,

I am just starting to work with the ARTEMIS/ATHENA software suite for EXAFS data processing and analysis and a newcomer in this mailing list. This project is really very nice and useful for the EXAFS community and I really enjoy to learn how to use it. I read most of the documents which are available on the website and around, but I have already two questions : 1) in the "feff.inp" command file, what are the options of the cards CONTROL and PRINTS 2) Running the FEFF6 software directly or through the Artemis bundle, I never get any "chi.dat" output file as a weighted sum of the individual "feffNNNN.dat" individual path contribution. Is there any forgotten option to get it ?

Thanks in advance for your help

Patrick
