ABINIT-MP is a user-friendly FMO program (by which 4-body fragments can be computed), especially for in-house Linux/Intel servers under the standard MPI environment. Additionally, the associated graphical user-interface system, BioStation Viewer (on Windows) helps the preparation of input data including the tedious fragmentation setting and also assists intuitive understanding of the target system through the inter-fragment interaction energies (IFIEs).
