Residue

A Residue is a group of atoms belonging to the same logical unit. They can be small molecules, amino-acids in a protein, monomers in polymers, etc.

Residue(name::String) -> Residue
Residue(name::String, id::Any) -> Residue

Create a new residue with the given name and optional residue identifier id.

Residue(topology::Topology, index::Integer) -> Residue

Get a copy of the residue at index from a topology.

The residue index in the topology is not always the same as the residue identifier.

contains(residue::Residue, index::Integer) -> Bool

Check if the atom at the given index is in the residue.

deepcopy(residue::Residue) -> Residue

Make a deep copy of a residue.

size(residue::Residue) -> Int64

Get the number of atoms in a residue.

add_atom!(residue::Residue, index::Integer)

Add the atom at the given index in the residue.

atoms(residue::Residue) -> Array{UInt64,1}

Get the atoms in a $residue$. This function returns a list of indexes.

id(residue::Residue) -> Int64

Get the identifier of a residue in the initial topology.

list_properties(residue::Residue) -> Array{String,1}

Get the names of all properties associated with a residue.

name(residue::Residue) -> String

Get the name of a residue.

properties_count(residue::Residue) -> Int64

Get the number of properties associated with a residue.

property(residue::Residue, name::String) -> Any

Get a named property for the given residue.

residue_for_atom(topology::Topology, index::Integer) -> Union{Nothing, Residue}

Get a copy of the residue containing the atom at index in the topology.

This function will return nothing if the atom is not in a residue, or if the index is bigger than the number of atoms in the topology.

set_property!(residue::Residue, name::String, value::Union{Bool, Float64, Array{Float64,1}, String})

Set a named property for the given residue.
