Dear all, I am using Atoms to calculate a Feff input file for CuFe2O4 spinel. However running Atoms/Feff results in program crash owing to 'two atoms very close together'. I modified the .cif file before importing (owing to partial occupancy issue) as following: Deleted: Fe2 Fe3+ 8 d 0.5 0.25 0.125 . 0.5 0 Modified: Cu1 Cu2+ 8 d 0.5 0.25 0.125 . 0.5 0 to Cu1 Cu2+ 8 d 0.5 0.25 0.125 . 1 0 After importing the file in Atoms, I also used different shift vectors (e.g. -0.125 -0.125 -0.125) but the issue is not resolved. Can someone help me please to solve this problem? Thanks. Best Regards Qasim
