Implemented operations#

The form adapter module molsysmt.form.openmm_State implements the following functions and modules:

Function / Module

Description

extract()

Extracts a subset of atoms, groups, or structures into a new openmm.State instance.

copy()

Creates an independent deep copy of the openmm.State object in memory.

add()

Adds elements from another system into an existing openmm.State instance.

merge()

Merges multiple systems into a single combined openmm.State object.

append_structures()

Appends new coordinate frames or trajectories to the structures container.

get_topological_attributes

Module containing getters for topological attributes.

get_structural_attributes

Module containing getters for structural attributes.

set

Module containing setters for updating coordinates, box dimensions, or attributes in-place.

iterators

Module providing iterators for streaming trajectory frames and structures.

has_attribute()

Checks whether a specific attribute name is supported by openmm.State.

is_form()

Returns True if the provided object is an instance of openmm.State.

Note

Each form adapter in MolSysMT implements only the specific functions that are meaningful for its data model.
