Upload your crystal structure (CIF, POSCAR, LMP) or retrieve it from MP, AFLOW, COD databases and automatically create desired concentrations of point defects (interstititals, vacancies, substitutes). 

• Interstitials can be introduced using either the Voronoi method (slower, suited for smaller structures) or a grid-based search (faster, suitable for larger structures)
• Defects can be placed at positions that are farthest apart, closest together, moderately spaced, or randomly distributed using greed points algorithm.
• More structures for the same point defect concentration can be generated at once with random seeds
• Structures can be download either in CIF, POSCAR, LMP, XYZ (with lattice) formats
