Calls read_geometry and creates a GeometryPlot from its output.

Parameters:

atoms (Atoms, optional) – the atoms to be associated with the Geometry
lattice (Lattice, optional) – the lattice to be associated with the geometry
axes – The axes to project the geometry to.
atoms – The atoms to plot. If None, all atoms are plotted.
atoms_style – List of style specifications for the atoms. See the showcase notebooks for examples.
atoms_scale – Scaling factor for the size of all atoms.
atoms_colorscale – Colorscale to use for the atoms in case the color attribute is an array of values. If None, the default colorscale is used for each backend.
drawing_mode – The method used to draw the atoms.
bind_bonds_to_ats – Whether to display only bonds between atoms that are being displayed.
points_per_bond – When the points are drawn using points instead of lines (e.g. in some frameworks to draw multicolor bonds), the number of points used per bond.
bonds_style – Style specification for the bonds. See the showcase notebooks for examples.
bonds_scale – Scaling factor for the width of all bonds.
bonds_colorscale – Colorscale to use for the bonds in case the color attribute is an array of values. If None, the default colorscale is used for each backend.
show_atoms – Whether to display the atoms.
show_bonds – Whether to display the bonds.
show_cell – Mode to display the cell. If False, the cell is not displayed.
cell_style – Style specification for the cell. See the showcase notebooks for examples.
nsc – Number of unit cells to display in each direction.
atoms_ndim_scale – Scaling factor for the size of the atoms for different dimensionalities (1D, 2D, 3D).
bonds_ndim_scale – Scaling factor for the width of the bonds for different dimensionalities (1D, 2D, 3D).
dataaxis_1d – Only meaningful for 1D plots. The data to plot on the Y axis.
arrows – List of arrow specifications to display. See the showcase notebooks for examples.
backend – The backend to use to generate the figure.

read(*args, **kwargs)

Generic read method which should be overloaded in child-classes

Parameters:: kwargs – keyword arguments will try and search for the attribute read_<> and call it with the remaining **kwargs as arguments.

read_basis() → Atoms

Returns a Atoms object from the XYZ file

Notes

This method defaults to return the first item(s).

This method enables slicing for handling multiple values (see [...|default]).

This is an optional handler enabling returning multiple elements if read_basis[...|0] allows this.

>>> single = obj.read_basis() # returns the default entry of read_basis[...|0]

To retrieve the first two elements that read_basis will return

>>> first_two = obj.read_basis[:2]()

Retrieving the last two is done equivalently:

>>> last_two = obj.read_basis[-2:]()

While one can store the sliced function tmp = obj.read_basis[:] one will loose the slice after each call.

read_geometry(atoms=None, lattice: Lattice | None = None) → Geometry

Returns Geometry object from the XYZ file

Parameters:

atoms (Atoms, optional) – the atoms to be associated with the Geometry
lattice (Lattice, optional) – the lattice to be associated with the geometry

Notes

This method defaults to return the first item(s).

This method enables slicing for handling multiple values (see [...|default]).

This is an optional handler enabling returning multiple elements if read_geometry[...|0] allows this.

>>> single = obj.read_geometry() # returns the default entry of read_geometry[...|0]

To retrieve the first two elements that read_geometry will return

>>> first_two = obj.read_geometry[:2]()

Retrieving the last two is done equivalently:

>>> last_two = obj.read_geometry[-2:]()

While one can store the sliced function tmp = obj.read_geometry[:] one will loose the slice after each call.

read_lattice() → Lattice

Returns a Lattice object from the XYZ file

Notes

This method defaults to return the first item(s).

This method enables slicing for handling multiple values (see [...|default]).

This is an optional handler enabling returning multiple elements if read_lattice[...|0] allows this.

>>> single = obj.read_lattice() # returns the default entry of read_lattice[...|0]

While one can store the sliced function tmp = obj.read_lattice[:] one will loose the slice after each call.

write(*args, **kwargs)

Generic write method which should be overloaded in child-classes

Parameters:: **kwargs – keyword arguments will try and search for the attribute write_ and call it with the remaining **kwargs as arguments.

write_geometry(geometry: Geometry, fmt: str = '.8f', comment: str | None = None)

Writes the geometry to the contained file in extxyz format

Parameters:

geometry – the geometry to be written
fmt – used format for the precision of the data
comment – if None, a sisl made comment that can be used for parsing the unit-cell is used else this comment will be written at the 2nd line.
