TimeseriesInput.__init__(file=None, sidecar=None, extra_def_dicts=None, name=None)[source]¶

Constructor for the TimeseriesInput class.

Parameters:

file (str or file like) – A tsv file to open.
sidecar (str or Sidecar) – A json sidecar to pull metadata from.
extra_def_dicts (DefinitionDict, list, or None) – Additional definition dictionaries.
name (str) – The name to display for this file for error purposes.

Notes

The extra_def_dicts are external definitions that override the ones in the object.

TimeseriesInput.assemble(mapper=None, skip_curly_braces=False)¶

Assembles the hed strings

Parameters:

mapper (ColumnMapper or None) – Generally pass none here unless you want special behavior.
skip_curly_braces (bool) – If True, don’t plug in curly brace values into columns.

Returns:

the assembled dataframe

Return type:

Dataframe

TimeseriesInput.column_metadata()¶

Get the metadata for each column

Returns:: number/ColumnMeta pairs
Return type:: dict

static TimeseriesInput.combine_dataframe(dataframe)¶

Combines all columns in the given dataframe into a single HED string series,: skipping empty columns and columns with empty strings.

Parameters:: dataframe (Dataframe) – The dataframe to combine
Returns:: the assembled series
Return type:: Series

TimeseriesInput.convert_to_form(hed_schema, tag_form)¶

Convert all tags in underlying dataframe to the specified form.

Parameters:

hed_schema (HedSchema) – The schema to use to convert tags.
tag_form (str) – HedTag property to convert tags to. Most cases should use convert_to_short or convert_to_long below.

TimeseriesInput.convert_to_long(hed_schema)¶

Convert all tags in underlying dataframe to long form.

Parameters:: hed_schema (HedSchema or None) – The schema to use to convert tags.

TimeseriesInput.convert_to_short(hed_schema)¶

Convert all tags in underlying dataframe to short form.

Parameters:: hed_schema (HedSchema) – The schema to use to convert tags.

TimeseriesInput.expand_defs(hed_schema, def_dict)¶

Shrinks any def-expand found in the underlying dataframe.

Parameters:

hed_schema (HedSchema or None) – The schema to use to identify defs
def_dict (DefinitionDict) – The definitions to expand

TimeseriesInput.get_column_refs()¶

Returns a list of column refs for this file.

Default implementation returns none.

Returns:: A list of unique column refs found
Return type:: column_refs(list)

TimeseriesInput.get_def_dict(hed_schema, extra_def_dicts=None)¶

Returns the definition dict for this file

Note: Baseclass implementation returns just extra_def_dicts.

Parameters:

hed_schema (HedSchema) – used to identify tags to find definitions(if needed)
extra_def_dicts (list, DefinitionDict, or None) – Extra dicts to add to the list.

Returns:

A single definition dict representing all the data(and extra def dicts)

Return type:

DefinitionDict

TimeseriesInput.get_worksheet(worksheet_name=None)¶

Get the requested worksheet.

Parameters:: worksheet_name (str or None) – The name of the requested worksheet by name or the first one if None.
Returns:: The workbook request.
Return type:: openpyxl.workbook.Workbook

Notes

If None, returns the first worksheet.

Parameters:: new_mapper (ColumnMapper) – A column mapper to be associated with this base input.

TimeseriesInput.set_cell(row_number, column_number, new_string_obj, tag_form='short_tag')¶

Replace the specified cell with transformed text.

Parameters:

row_number (int) – The row number of the spreadsheet to set.

Notes

Any attribute of a HedTag that returns a string is a valid value of tag_form.

Raises:
