EDAX TEAM/Genesis (SPC, SPD)
----------------------------
RosettaSciIO can read both ``.spd`` (spectrum image) and ``.spc`` (single spectra)
files from the EDAX TEAM software and its predecessor EDAX Genesis.
If reading an ``.spd`` file, the calibration of the
spectrum image is loaded from the corresponding ``.ipr`` and ``.spc`` files
stored in the same directory, or from specific files indicated by the user.
If these calibration files are not available, the data from the ``.spd``
file will still be loaded, but with no spatial or energy calibration.
When using `HyperSpy <https://hyperspy.org>`_, if elemental information has been
defined in the spectrum image, those elements will automatically be added to the
signal loaded by HyperSpy.
In HyperSpy, if an ``.spd`` file is loaded, the result will be a HyperSpy
``EDSSEMSpectrum`` map, and the calibration will be loaded from the appropriate
``.spc`` and ``.ipr`` files (if available). If an ``.spc`` file is loaded, the
result will be a single ``EDSSEMSpectrum`` with no other files needed for
calibration.
.. Note ::
Currently, HyperSpy will load data as an ``EDSSEMSpectrum`` signal. If support
for TEM EDS data is needed, please open an issue in the `issues tracker
<https://github.com/hyperspy/rosettasciio/issues>`_ to alert the developers
of the need.
For reference, :ref:`file specifications <edax-file_specification>` for the EDAX
file formats have been publicly available from EDAX.
