Features Efficient generation of Fermi-orbital descriptors Generation typically takes seconds Allows for any kind of bond arrangement to be initialized One can distinguish different bond orders; important when the bond order is unclear (double bond, triple bonds, etc.) Minimal input: User only needs to provide information about multiple bonds All single bonds are automatically initialized Lone FODs are initialized automatically. This usually works well, but there are cases where it doesn't. Always double-check the generated guess! Highly symmetry guesses Trying to obtain the best possible starting guesses for FLO-SIC calculations Periodic boundary conditions are available Future developments Better structural motifs for core FODs (especially for transitions metals and beyond); current understanding of these systems is limited.
