empyer.io module

empyer.io.load(filenames=None, signal_type=None, stack=False, stack_axis=None, new_axis_name='stack_element', lazy=False, **kwds)

Extends the hyperspy loading functionality with additional ability to load empyer signals.

Parameters:

• filenames (list) – The list of file paths or single file to be loaded
• signal_type (str) – The type of signal to be loaded. Can be read from file or given
• stack (bool) – Stack creates a new axis and loads a list of files into one signal
• stack_axis
• new_axis_name (str) – The name of the new axis created with stack
• lazy (bool) – Load the signal into memory or load chunks. May effect performance, but useful for large datasets.

Returns:

A signal of type signal_type

Return type:

signal
