config

Common configuration models.

Classes:

• FEP –

  Configure modifying a system to be scalable by FEP lambdas.

• Edge –

  Defines a basic edge in a free energy network.

• Network –

  Defines a basic free energy network.

Attributes:

• DEFAULT_INITIAL_TEMPERATURE –

  The default temperature to begin annealing from during equilibration

• LigandReferenceMethod –

  The method to use when automatically selecting ligand atoms to use in alignment

DEFAULT_INITIAL_TEMPERATURE module-attribute

DEFAULT_INITIAL_TEMPERATURE = 50.0 * kelvin

The default temperature to begin annealing from during equilibration

LigandReferenceMethod module-attribute

LigandReferenceMethod = Literal['chen', 'baumann']

The method to use when automatically selecting ligand atoms to use in alignment restraints.

FEP pydantic-model

Bases: BaseModel

Configure modifying a system to be scalable by FEP lambdas.

Fields:

• scale_vdw (bool)
• scale_charges (bool)
• ligands_can_interact (bool)

scale_vdw pydantic-field

scale_vdw: bool = True

Whether to scale the vdW non-bonded interactions.

scale_charges pydantic-field

scale_charges: bool = True

Whether to scale the electrostatic non-bonded interactions.

ligands_can_interact pydantic-field

ligands_can_interact: bool = False

Whether ligands are allowed to interact with each other.

Edge pydantic-model

Bases: BaseModel

Defines a basic edge in a free energy network.

Fields:

• ligand_1 (str)
• ligand_2 (str | None)
• ligand_1_metadata (dict[str, Any])
• ligand_2_metadata (dict[str, Any])

ligand_1 pydantic-field

ligand_1: str

The name of the first ligand.

ligand_2 pydantic-field

ligand_2: str | None

The name of the second ligand. This should be None if running an ABFE calculation.

ligand_1_metadata pydantic-field

ligand_1_metadata: dict[str, Any]

Any additional metadata about ligand 1.

ligand_2_metadata pydantic-field

ligand_2_metadata: dict[str, Any]

Any additional metadata about ligand 2.

Network pydantic-model

Bases: BaseModel

Defines a basic free energy network.

Fields:

• receptor (str | None)
• edges (list[Edge])
• receptor_metadata (dict[str, Any])

receptor pydantic-field

receptor: str | None = None

The name of the receptor. If None, the receptor will be identified from the input directory structure

edges pydantic-field

edges: list[Edge]

The edges in the free energy network.

receptor_metadata pydantic-field

receptor_metadata: dict[str, Any]

Any additional metadata about the receptor.
