The development of g_mmpbsa package is initiated under Open Source Drug Discovery Consortium (OSDD), which is a collaborative platform to design and discover new drugs for neglected tropical diseases such as Malaria, Tuberculosis, Leshmaniasis etc.

g_mmpbsa is developed using two widely used open source software i.e. GROMACS and APBS and it has similar user interface like other GROMACS tools.

The tool calculates components of binding energy using MM-PBSA method except the entropic term and energetic contribution of each residue to the binding using energy decomposition scheme.

The output from the tool is used further as input in python scripts which is provided in this package, to get the final binding energy and energetic contribution of each residue.

• It is an open source tool and can be modified under the terms of the GNU public license

• It is implemented through open source software GROMACS and APBS, making it accessible to large number of users.

• Supports GROMACS 4.5.x, 4.6.x and 5.0.x versions.

• Supports APBS 1.2.x, 1.3.x and 1.4.x versions

• Inherits APBS capability of parallel computation using OpenMP. See details here.

• Supports external APBS execuatble with mpirun for parallel computation on HPC. See details here.

• Options for van der Waal radii that are used for solvation free energy calculation using implicit solvent models.

• Options for several non-polar solvation model such as SASA, SAV and Weeks–Chandler–Andersen (WCA).

• Options for calculating contribution of each residue in the net binding energy.

• Simultaneous computations of binding energy components and residue wise energy contribution, and thus it is computationally less expensive.

• This tool can be modified and/or redistributed under terms of GNU public license.
