Dear List, For a vacancy, creating another atomic species with a negative value and giving it a coordinate is recommended. Is there supposed to be a pseudopotential file for the ghost atom? How is it generated? Do the blocks below look correct for the ghost/vacancy? %block ChemicalSpeciesLabel 1 8 O 2 -8 O_Ghost
