Implemented operations#

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

Function / Module

Description

extract()

Extracts a subset of atoms, groups, or structures into a new MDAnalysis.Universe instance.

copy()

Creates an independent deep copy of the MDAnalysis.Universe object in memory.

add()

Adds elements from another system into an existing MDAnalysis.Universe instance.

merge()

Merges multiple systems into a single combined MDAnalysis.Universe 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 MDAnalysis.Universe.

is_form()

Returns True if the provided object is an instance of MDAnalysis.Universe.

Note

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