erlab.io.characterization.xrd¶

Functions related to loading x-ray diffraction spectra.

Currently only supports loading raw data from igor .itx files.

Functions

load_xrd_itx(path, **kwargs)

Load x-ray diffraction spectra from .itx file for Igor pro.

erlab.io.characterization.xrd.load_xrd_itx(path, **kwargs)[source]¶

Load x-ray diffraction spectra from .itx file for Igor pro.

Parameters:

path (str) – Local path to .itx file.
**kwargs – Extra arguments to open.

Returns:

Dataset object containing data from the file.

Return type:

xarray.Dataset

Note

By default, the file is read with the 'windows-1252' encoding. This behavior can be customized by supplying keyword arguments.

Examples

Load from file:

>>> xrd_data = load_xrd_itx("/path/to/example_data.itx")
>>> xrd_data
