spectrochempy.read_carroucell

read_carroucell(directory=None, **kwargs)[source]

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 (keyword parameters, optional) – See Other Parameters.

Returns

object (NDDataset or list of NDDataset) – The returned dataset(s).

Other Parameters

  • spectra (array-like 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) .
