Dear Bruce Ravel, Hello, I am Moneeb Shatnawi from the University of Jordan. I have a question and I appreciate your help in advance. I have installed the Demeter program (version 0.9.18) and I tried to use your (D)Atoms program using the attached input files. When I try to run atoms, I get a warning message stating that two sites generate one or more common positions and their occupancies sum to more than 1. (attached also the warning message that I got). If I ignore this warning message and try to run FEFF, the program crashes. When I change the space group to P 1 (as indicated by the message) , the program runs well. My question is, could you please figure out the problem with these input files, so that I can run them with the correct space group? Thank you so much in advance, Moneeb
