class soprano.properties.basic.basic.CalcEnergy(name=None, **params)

Bases: AtomsProperty

Property representing the energy calculated by an ASE calulator

Initialize an AtomsProperty and set its parameters. The AtomsProperty instance can then be called with a structure as its only argument to get the property with the given parameters.

Args:

name (str): a name to give to this specific instance of the

property (will be used to store it as array if

requested)

params: named arguments specific to this type of property

__call__(s, store_array=False)

Calling the AtomsProperty returns the value of the property as extracted with the parameters of this specific instance.

Args:

s (ase.Atoms or AtomsCollection): the structure or collection

from which to extract the

property

store_array (bool): if s is a collection, whether to store the

resulting data as an array in the collection

using the given name for this instance

Returns:

property: the value of the property for the given structure or

a list of values if a collection has been passed

static extract(s)

Extract the given property with given parameters from an Atoms object.

Args:

Returns:

property: the value of the property for the given structure and

parameters

classmethod get(s, store_array=False, **kwargs)

Extract the given property using the default parameters on an Atoms object s

Args:

s (ase.Atoms or AtomsCollection): the structure or collection

from which to extract the
