Dear All, I think I may have found a possible bug with the stand-alone version of (D) Atoms. If I generate an inp file in atoms, save it and then try and run feff on it later, Atoms crashes without attempting the calculation. However, if I load that same input file in (D)Artemis it will run feff without crashing. Stand-alone atoms will also fail if I generate the input file in Artemis, save it and then try and later open it using Atoms. Only Atoms or Artemis is open at a time, This problem is occurring on both 32 and 64 bit Windows 7 computers running the current (0.9.18.2) package. The problem occurred using 0.9.17 also. Any ideas of why I am all of a sudden having this issue when it has not been a problem before? The cif file, inp file, and atoms log file are all attached. Sincerely, Matt Frith
