ElementFilter

pydantic model openff.qcsubmit.workflow_components.ElementFilter[source]

Filter the molecules based on a list of allowed elements.

Note

The allowed_elements attribute can take a list of either symbols or atomic numbers and will resolve them to a common internal format as required.

Example

Using atomic symbols or atomic numbers in components.

`python >>> from openff.qcsubmit.workflow_components import ElementFilter >>> efil = ElementFilter() # set the allowed elements to H,C,N,O >>> efil.allowed_elements = ['H', 'C', 'N', 'O'] >>> efil.allowed_elements = [1, 6, 7, 8] `

Config
  • allow_mutation: bool = True

  • validate_assignment: bool = True

Fields
  • allowed_elements (List[Union[int, str]])

  • type (Literal['ElementFilter'])

Validators

field type: Literal['ElementFilter'] = 'ElementFilter'
field allowed_elements: List[Union[int, str]] = ['H', 'C', 'N', 'O', 'F', 'P', 'S', 'Cl', 'Br', 'I']

The list of allowed elements as symbols or atomic number ints.

Validated by
  • check_allowed_elements

classmethod description()[source]

Returns a friendly description of the workflow component.

Return type

str

classmethod fail_reason()[source]

Returns a friendly description of why a molecule would fail to pass the component.

Return type

str

classmethod properties()[source]

Returns the runtime properties of the component such as parallel safe.

Return type

openff.qcsubmit.common_structures.ComponentProperties

provenance(toolkit_registry)[source]

Generate version information for all of the software used during the running of this component.

Returns

A dictionary of all of the software used in the component along wither their version numbers.

Parameters

toolkit_registry (openff.toolkit.utils.toolkit_registry.ToolkitRegistry) –

Return type

Dict

Note

The element class in OpenMM is used to match the elements so the OpenMM version is given.
