class fusor.harvester.FusionCallerHarvester

ABC for fusion caller harvesters

column_rename: dict

delimeter: str

fusion_caller: FusionCaller

load_records(fusion_path)

Convert rows of fusion caller output to Pydantic classes

Parameters:

• fusion_path (Path) – The path to the fusions file

• column_rename – A dictionary of column mappings

• delimeter – The delimeter for the fusions file

Raises:

ValueError – if the file does not exist at the specified path

Return type:

list[FusionCaller]

Returns:

A list of fusions, represented as Pydantic objects
