||Proteins, DNA/RNA, biopolymers, composites of low molecular weight organic compounds, and molecular aggregates
|Physical quantities that can be computed
||Total energy, energy gradient, Mulliken population, interaction energy between fragments, pair interaction energy (PIE) and its decomposition (PIEDA), electron density distribution (output as a cube file), solvation free energy, and electron excitation energy calculated using continuous dielectric models
||Fragment molecular orbital (FMO) method
||Parallel computing by MPI is supported (an interface DDI provided by GAMESS developers is used as a rapper).

||The system is divided into small fragments; ab initio MO calculation is performed on fragment pairs; the results are then used to compute the properties of the entire systems. Calculation time is more or less proportional to the system size.
