ChemicalSystem

class gufe.chemicalsystem.ChemicalSystem(components: dict[str, Component], name: str | None = '')

A combination of Components that form a system

Containing a combination of SmallMoleculeComponent, SolventComponent and ProteinComponent, this object typically represents all the molecules in a simulation box.

Used as a node for an AlchemicalNetwork.

Parameters:

• components – The molecular representation of the chemical state, including connectivity and coordinates. Given as a dict with user-defined labels as keys, Components as values.

• name – Optional identifier for the chemical state; included with the other attributes as part of the (hashable) graph node itself when the chemical state is added to an AlchemicalNetwork.

Attributes

components	The individual components of the chemical system.
name	Optional identifier for the chemical system.
total_charge	Formal charge for the ChemicalSystem.

property components: dict[str, Component]

The individual components of the chemical system.

Components include atomic connectivity and coordinates. This is a dict with user-defined labels as keys and Component instances as values.

property name

Optional identifier for the chemical system.

Used as part of the (hashable) graph node itself when the chemical state is added to an AlchemicalNetwork.

property total_charge

Formal charge for the ChemicalSystem.
