    .. class:: infomark

    **What it does**

    This tool converts parameter and topology files that represent a solvated complex into parameter files for the ligand, receptor, complex and solvated complex in AMBER prmtop format. These files are needed for MMPBSA calculations.

    .. class:: infomark

    **How it works**

    AmberTools ParmEd is used to strip unneeded atoms and save out the parameter files. The stripmasks are defined by the user.

    .. class:: infomark

    **Outputs created**

    prmtop files for the ligand, receptor, complex and solvated complex.

    .. class:: infomark
