add_reactions(stoichiometries, program, singlepoint_specification, optimization_specification, keywords, tag='*', priority=PriorityEnum.normal, owner_group=None, find_existing=True)[source]#

Adds new reaction computations to the server

Reactions can have a singlepoint specification, optimization specification, or both; at least one must be specified. If both are specified, an optimization is done, followed by a singlepoint computation. Otherwise, only the specification that is specified is used.

This checks if the calculations already exist in the database. If so, it returns the existing id, otherwise it will insert it and return the new id.

This will add one record per set of molecules

Parameters:
  • stoichiometries (Sequence[Sequence[Sequence[float, Union[int, Molecule]]]]) – Coefficients and molecules of the reaction. Each reaction has multiple molecules/coefficients, so this is a nested list

  • program (str) – The program for running the reaction computation (“reaction”)

  • singlepoint_specification (Optional[QCSpecification]) – The specification for singlepoint energy calculations

  • optimization_specification (Optional[OptimizationSpecification]) – The specification for optimization calculations

  • keywords (ReactionKeywords) – The keywords for the reaction calculation/service

  • tag (str) – The tag for the task. This will assist in routing to appropriate compute managers.

  • priority (PriorityEnum) – The priority of the job (high, normal, low). Default is normal.

  • owner_group (Optional[str]) – Group with additional permission for these records

  • find_existing (bool) – If True, search for existing records and return those. If False, always add new records

Returns:

Metadata about the insertion, and a list of record ids. The ids will be in the order of the input molecules

Return type:

Tuple[InsertMetadata, List[int]]

get_reactions(record_ids, missing_ok=False, *, include=None)[source]#

  • include (Iterable[str] | None) – Additional fields to include in the returned record

Returns:

If a single ID was specified, returns just that record. Otherwise, returns a list of records. If missing_ok was specified, None will be substituted for a record that was not found.
