Implemented operations#

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

Function / Module

Description

extract()

Extracts a subset of atoms, groups, or structures into a new file:fasta instance.

copy()

Creates an independent deep copy of the file:fasta object in memory.

add()

Adds elements from another system into an existing file:fasta instance.

merge()

Merges multiple systems into a single combined file:fasta object.

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 file:fasta.

is_form()

Returns True if the provided object is an instance of file:fasta.

Note

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