class sisl.io.cubeSile(filename, mode='r', comment=None, *args, **kwargs)

Bases: sisl.io.Sile

CUBE file object

Methods

dir_file([filename, filename_base])	File of the current Sile
read(*args, **kwargs)	Generic read method which should be overloaded in child-classes
read_geometry()	Returns Geometry object from the CUBE file
read_grid([imag])	Returns Grid object from the CUBE file
read_supercell([na])	Returns SuperCell object from the CUBE file
write(*args, **kwargs)	Generic write method which should be overloaded in child-classes
write_geometry(geometry[, fmt, size, origin])	Writes Geometry object attached to this grid
write_grid(grid[, fmt, imag])	Write Grid to the contained file
write_supercell(sc[, fmt, size, origin])	Writes SuperCell object attached to this grid
base_file	File of the current Sile
file	File of the current Sile

__init__(filename, mode='r', comment=None, *args, **kwargs)

property base_file

File of the current Sile

dir_file(filename=None, filename_base='')

File of the current Sile

property file

File of the current Sile

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_geometry()

Returns Geometry object from the CUBE file

read_grid(imag=None)

Returns Grid object from the CUBE file

Parameters

imag (str or Sile or Grid) – the imaginary part of the grid. If the geometries does not match an error will be raised.

read_supercell(na=False)

Returns SuperCell object from the CUBE file

Parameters

na (bool, optional) – whether to also return the number of atoms in the geometry

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, fmt='15.10e', size=None, origin=None, *args, **kwargs)

Writes Geometry object attached to this grid

Parameters

• geometry (Geometry) – geometry to be written

• fmt (str, optional) – floating point format for stored values

• size ((3, ), optional) – shape of the stored grid ([1, 1, 1])

• origin ((3, ), optional) – origin of the cell ([0, 0, 0])

write_grid(grid, fmt='.5e', imag=False, *args, **kwargs)

Write Grid to the contained file

Parameters

• grid (Grid) – the grid to be written in the CUBE file

• fmt (str, optional) – format used for precision output

• imag (bool, optional) – write only imaginary part of the grid, default to only writing the real part.

• buffersize (int, optional) – size of the buffer while writing the data, (6144)

write_supercell(sc, fmt='15.10e', size=None, origin=None, *args, **kwargs)

Writes SuperCell object attached to this grid

Parameters

• sc (SuperCell) – supercell to be written

• fmt (str, optional) – floating point format for stored values

• size ((3, ), optional) – shape of the stored grid ([1, 1, 1])

• origin ((3, ), optional) – origin of the cell ([0, 0, 0])
