kikuchipy.io.plugins.emsoft_ebsd_master_pattern.file_reader(filename: str | Path, energy: range | None = None, projection: str = 'stereographic', hemisphere: str = 'upper', lazy: bool = False, **kwargs) → List[dict][source]#

Read simulated electron backscatter diffraction master patterns from EMsoft’s HDF5 file format [Callahan and De Graef, 2013].

Not meant to be used directly; use load().

Parameters:

filename: Full file path of the HDF file.
energy: Desired beam energy or energy range. If not given (default), all available energies are read.
projection: Projection(s) to read. Options are "stereographic" (default) or "lambert".
hemisphere: Projection hemisphere(s) to read. Options are "upper" (default), "lower" or "both". If "both", these will be stacked in the vertical navigation axis.
lazy: Open the data lazily without actually reading the data from disk until requested. Allows opening datasets larger than available memory. Default is False.
**kwargs: Keyword arguments passed to h5py.File.

Returns:

signal_dict_list: Data, axes, metadata and original metadata.
