BioSimSpace.FreeEnergy.Binding

class BioSimSpace.FreeEnergy.Binding(system, protocol=None, box=None, free_leg=True, work_dir=None, engine=None, property_map={})

A class for configuring and running binding free energy simulations.

__init__(system, protocol=None, box=None, free_leg=True, work_dir=None, engine=None, property_map={})

Constructor.

Parameters

• system (System) – The molecular system.

• protocol (Protocol.FreeEnergy) – The simulation protocol.

• box ([Length]) – A list containing the box size in each dimension. This box will be used for the “free” leg of the simulation, which typically can be run with a significantly smaller box than the “bound” leg.

• free_leg (bool) – Whether to simulation the free leg of the simulation. Set to False if you only wish to run the bound leg.

• work_dir (str) – The working directory for the simulation.

• engine (str) – The molecular dynamics engine used to run the simulation. Available options are “GROMACS”, or “SOMD”. If this argument is omitted then BioSimSpace will choose an appropriate engine for you.

• property_map (dict) – A dictionary that maps system “properties” to their user defined values. This allows the user to refer to properties with their own naming scheme, e.g. { “charge” : “my-charge” }
