spectrochempy.read_carroucell

read_carroucell(directory=None, **kwargs)

Open .spa files in a directory after a carroucell experiment.

The files for a given sample are grouped in NDDatasets (sorted by acquisition date). The NDDatasets are returned in a list sorted by sample number. When the file containing the temperature data is present, the temperature is read and assigned as a label to each spectrum.

Parameters

• directory (str, optional) – If not specified, opens a dialog box.

• **kwargs – Optional keyword parameters. See Other Parameters.

Other Parameters

• spectra (arraylike of 2 int (min, max), optional, default=None) –

  The first and last spectrum to be loaded as determined by their number.

  If None all spectra are loaded.

• discardbg (bool, optional, default=True) – If True : do not load background (sample #9).

• delta_clocks (int, optional, default=0) – Difference in seconds between the clocks used for spectra and temperature acquisition. Defined as t(thermocouple clock) - t(spectrometer clock).

Returns

nddataset – NDDataset or list of NDDataset .

Notes

All files are expected to be present in the same directory and their filenames are expected to be in the format : X_samplename_YYY.spa and for the background files : X_BCKG_YYYBG.spa where X is the sample holder number and YYY the spectrum number.
