Tautomer Search

Tautomer-search workflow - find tautomeric forms of molecules.

Tautomer dataclass

Tautomer(
    energy: float,
    weight: float,
    predicted_relative_energy: float,
    structure_uuids: tuple[str, ...],
)

Tautomer result.

Parameters:

Name	Type	Description	Default
energy	float	Energy in Hartree.	required
weight	float	Boltzmann weight (sum to 1.0 across all tautomers).	required
predicted_relative_energy	float	Relative energy in kcal/mol (relative to lowest energy).	required
structure_uuids	tuple[str, ...]	UUIDs of the structure calculations.	required

TautomerResult dataclass

TautomerResult(
    workflow_data: dict[str, Any],
    workflow_type: str,
    workflow_uuid: str,
    complete: bool = True,
)

Bases: WorkflowResult

Result from a tautomer-search workflow.

tautomers property

tautomers: list[Tautomer]

List of tautomers with energies and weights.

messages property

messages: list[Message]

Any messages or warnings from the workflow.

best_tautomer property

best_tautomer: Molecule | None

Molecule of the highest Boltzmann-weight tautomer.

molecules property

molecules: list[Molecule]

Molecules for all tautomers.

.. note:: Makes one API call per tautomer on first access. Results are cached. Call clear_cache() to refresh.

name	str	Name of the workflow.	'Tautomer Search Workflow'
folder_uuid	str | None	UUID of the folder to place the workflow in.	None
folder	Folder | None	Folder object to store the workflow in.	None
max_credits	int | None	Maximum number of credits to use for the workflow.	None
webhook_url	str | None	URL that Rowan will POST to when the workflow completes.	None
is_draft	bool	If True, submit the workflow as a draft without starting execution.	False

Returns:

Type	Description
Workflow	Workflow object representing the submitted workflow.

Raises:
