Base Record#
A record is an object that represents a single computation. Records can be simple, such as a singlepoint record or complex with lots of subrecords of different types (such as a NEB record.
However, all records share a set of common methods and properties.
Records can be submitted, retrieved, and modified using the QCPortal client.
Tip
All records are Pydantic models, and so incorporates all the features from that library.
Metadata#
ID, status, created_on, modified_on, comments, owner_user, owner_group, extras
Computation History#
compute_history, manager_name, provenance, stdout, stderr, error, native_files

- compile_values(value_call, value_names='value', entry_names=None, specification_names=None, unpack=False)[source]#
Compile values from records into a pandas DataFrame.
- Parameters:
value_call (Callable) – Function to call on each record to extract the desired value. Must return a scalar value or a sequence of values if ‘unpack’ is set to True.
value_names (Sequence[str] | str) – Column name(s) for the extracted value(s). If a string is provided and multiple values are returned by ‘value_call’, columns are named by appending an index to this string. If a list of strings is provided, it must match the length of the sequence returned by ‘value_call’. Default is “value”.
entry_names (str | Iterable[str] | None) – Entry names to filter records. If not provided, considers all entries.
specification_names (str | Iterable[str] | None) – Specification names to filter records. If not provided, considers all specifications.
unpack (bool) – If True, unpack the sequence of values returned by ‘value_call’ into separate columns. Default is False.
- Returns:
A multi-index DataFrame where each row corresponds to an entry. Each column corresponds has a top level index as a specification, and a second level index as the appropriate value name. Values are extracted from records using ‘value_call’.
- Return type:
pd.DataFrame
- Raises:
ValueError – If the length of ‘value_names’ does not match the number of values returned by ‘value_call’ when ‘unpack’ is set to True.
Notes
The DataFrame is structured such that the rows are entries and columns are specifications.
2. If ‘unpack’ is True, the function assumes ‘value_call’ returns a sequence of values that need to be distributed across columns in the resulting DataFrame. ‘value_call’ should always return the same number of values for each record if unpack is True.
- get_properties_df(properties_list)[source]#
Retrieve a DataFrame populated with the specified properties from dataset records.
This function uses the provided list of property names to extract corresponding values from each record’s properties. It returns a DataFrame where rows represent each record. Each column corresponds has a top level index as a specification, and a second level index as the appropriate value name. Columns with all NaN values are dropped.
Parameters:#
- properties_list
List of property names to retrieve from the records.
Returns:#
- pd.DataFrame
A DataFrame populated with the specified properties for each record.
- Parameters:
properties_list (Sequence[str])
- Return type:
DataFrame
- refresh_cache(entry_names=None, specification_names=None)[source]#

This can be used to fix some inconsistencies in the cache without deleting and starting over. For example, this can fix instances where the record attached to a given entry & specification has changed (new record id) due to renaming specifications and entries, or via remove_records followed by a submit without duplicate checking.
This will also fetch any updated records
- Parameters:
entry_names (str | Iterable[str] | None) – Names of the entries whose records to fetch. If None, fetch all entries
