spectrochempy.read_quadera¶

read_quadera(*paths, **kwargs)[source]¶

Read a Pfeiffer Vacuum’s QUADERA® mass spectrometer software file with extension .asc.

Parameters

*paths (str, pathlib.Path object, list of str, or list of pathlib.Path objects, optional) – The data source(s) can be specified by the name or a list of name for the file(s) to be loaded:

e.g.,( file1, file2, …, **kwargs )

If the list of filenames are enclosed into brackets:

e.g., ( [ file1, file2, … ], **kwargs )

The returned datasets are merged to form a single dataset, except if merge is set to False. If a source is not provided (i.e. no filename, nor content), a dialog box will be opened to select files.
**kwargs – Optional keyword parameters (see Other Parameters).

Returns

read_quadera – NDDataset or list of NDDataset .

Other Parameters

timestamp (bool, optional) – returns the acquisition timestamp as Coord (Default=True). If set to false, returns the time relative to the acquisition time of the data
protocol ({‘scp’, ‘omnic’, ‘opus’, ‘topspin’, ‘matlab’, ‘jcamp’, ‘csv’, ‘excel’, ‘asc’}, optional) – Protocol used for reading. If not provided, the correct protocol is inferred (whnever it is possible) from the file name extension.
directory (str, optional) – From where to read the specified filename. If not specified, read in the default datadir specified in SpectroChemPy Preferences.
merge (bool, optional) – Default value is False. If True, and several filenames have been provided as arguments, then a single dataset with merged (stacked along the first dimension) is returned (default=False)
description (str, optional) – A Custom description.
content (bytes object, optional) – Instead of passing a filename for further reading, a bytes content can be directly provided as bytes objects. The most convenient way is to use a dictionary. This feature is particularly useful for a GUI Dash application to handle drag and drop of files into a Browser. For examples on how to use this feature, one can look in the tests/tests_readers directory
listdir (bool, optional) – If True and filename is None, all files present in the provided directory are returned (and merged if merge is True. It is assumed that all the files correspond to current reading protocol (default=True)
recursive (bool, optional) – Read also in subfolders. (default=False)

Notes

Currently the acquisition time is that of the first channel as the timeshift of other channels are typically within few seconds, and the data of other channels are NOT interpolated Todo: check with users whether data interpolation should be made
