    .. class:: infomark

    **What it does**

    This tool calculates the Molecular Mechanics Poisson-Boltzman Surface Area (MMPBSA) which is an estimate of the binding free energy between a ligand and a receptor.

    .. class:: infomark

    **How it works**

    Prior to using this tool simulations of the ligand complexed with the receptor must be run. This tool, which wraps AmberTools will need a prmtop (Amber style parameter topology file for the receptor, ligand and the complex) and the trajectory in netCDF format.

    - Single Trajectory Estimate: A simulation of the complex in water is run in advance. The trajectory of this complex is used to estimate the MMPBSA or MMGBSA depending on the options chosen. A General Born (GB) calculation is recommended as this calculation finishes quickly.
    - Multiple Trajectory Estimate: A simulation of the complex in water, the receptor in water and the ligand in water are run in advance. This is useful the ligand is expected to have a significantly different conformation in solution vs in the complex. The trajectory of this complex is used to estimate the MMPBSA or MMGBSA depending on the options chosen. A General Born (GB) calculation is recommended as this calculation finishes quickly.

    .. class:: infomark

    **Outputs created**

    - The statistics file which includes all information about the frames analysed and average energies. The DELTA G binding is estimated. If negative this is a favourable binding. Note that by default the entropy contribution to binding (unfavourable) is not calculated. A normal mode analysis is needed.
    - The decomposition file contains a breakdown of each residues contribution to the energy. For example using the default Energy Decomposition Scheme (1) the interaction of each residue with the rest of the system is calculated and listed.
    - The parameter file contains the input parameters passed from Galaxy to MMPBSA.py in the expected MMPBSA input format.

    .. class:: infomark

    **User guide and documentation**

    - The `AmberTools Manual`_
    - The `Amber Tutorial`_ on using MMPBSA.py
    - There are many more complex flags available. This Galaxy wrapper only supports GB and PB binding free energies and decomposition. Parallel calculations are not supported at present.
    - This Galaxy tool is based on MMPBSA.py. More details on options that are not details in the Manual and Tutorials can be found in the code - see "$CONDA_PREFIX/lib/python3.7/site-packages/MMPBSA_mods/input_parser.py" and "$CONDA_PREFIX/lib/python3.7/site-packages/MMPBSA_mods/main.py".

    .. class:: infomark

    **Test data**

    - The test data for this tool comes from an `Amber Tutorial`_ and the original dataset_ is available.
    - For convenience, water has been stripped from the .mdcrd trajectory and this has been converted to netcdf format.

    .. code-block:: python

      import mdtraj as md
      traj = md.load('1err_prod.mdcrd', top='1err.solvated.prmtop')
      topology = traj.topology
      atoms_to_keep = topology.select('not water')
      traj.restrict_atoms(atoms_to_keep)
      traj.save('1err_desolvated.nc')
      traj[0:2].save('1err_desolvated_mini.nc')

.. class:: infomark

**What it does**

This tool calculates the Molecular Mechanics Poisson-Boltzman Surface Area (MMPBSA), which is an estimate of the binding free energy between a ligand and a receptor. It also can calculate the MMGBSA, which is a common alternative, replacing the Poisson-Boltzmann term with the General Born approximation.

.. class:: infomark

**How it works**

Prior to using this tool, simulations of the ligand complexed with the receptor must be run. This tool, which wraps AmberTools, requires a prmtop (Amber parameter topology) file for the receptor, ligand and the complex and the trajectory in netCDF format.

- Single Trajectory Estimate: A single simulation of the complex in water is run. The trajectory of this complex is used to estimate the MMPBSA or MMGBSA, depending on the options chosen.
- Multiple Trajectory Estimate: Separate simulations of the complex in water, the receptor in water and the ligand in water are run. This is useful if the ligand (or receptor) is expected to have a significantly different conformation in solution compared to in the complex, but is otherwise not recommended as it increases the uncertainty of the results. The trajectories are used to estimate the MMPBSA or MMGBSA depending on the options chosen.

If simulations were performed using the Galaxy GROMACS tools, the topology (in top format) and trajectories (in xtc format) can be converted to Amber prmtop and netcdf formats using the Convert Parameters and MDTraj file converter tools respectively.

.. class:: infomark

**Outputs created**

- The statistics file which includes all information about the frames analysed and average energies. The DELTA G binding is estimated. If negative this is a favourable binding. Note that by default the entropy contribution to binding (unfavourable) is not calculated. A normal mode analysis is needed.
- The parameter file contains the input parameters passed from Galaxy to MMPBSA.py in the expected MMPBSA input format.
- (Optional, if decomposition analysis is performed) The decomposition file contains a breakdown of each residue's contribution to the energy. For example, using the default energy decomposition scheme (1) the interaction of each residue with the rest of the system is calculated and listed.
- (Optional, if the "Keep additional files?" option is chosen) A collection containing all temporary files generated in the course of the calculation. This may be useful for debugging.

**User guide and documentation**

- The `AmberTools Manual`_
- The `Amber Tutorial`_ on using MMPBSA.py
- There are many more complex flags available. This Galaxy wrapper only supports GB and PB binding free energies and decomposition. Parallel calculations are not supported at present.
