spectrochempy.read_labspec

read_labspec(*paths, **kwargs)[source]

Read a single Raman spectrum or a series of Raman spectra.

Files to open are .txt file created by Labspec software. Non-labspec .txt files are ignored (return None)

Parameters:

*paths (str, Path object objects or valid urls, 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., ( filename1, filename2, …, kwargs )
If the list of filenames are enclosed into brackets:
- e.g., ( [filename1, filename2, …], kwargs )
The returned datasets are merged to form a single dataset, except if merge is set to False.
**kwargs (keyword parameters, optional) – See Other Parameters.

Returns:

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

Other Parameters:

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.
csv_delimiter (str, optional, default: csv_delimiter) – Set the column delimiter in CSV file.
description (str, optional) – A Custom description.
directory (Path object objects or valid urls, optional) – From where to read the files.
download_only (bool, optional, default: False) – Used only when url are specified. If True, only downloading and saving of the files is performed, with no attempt to read their content.
merge (bool, optional, default: False) – If True and several filenames or a directory have been provided as arguments, then a single NDDataset with merged dataset (stacked along the first dimension) is returned. In the case not all datasets have compatible dimensions or types/origins, then several NDDatasets can be returned for different groups of compatible datasets.
origin (str, optional) – If provided it may be used to define the type of experiment: e.g., ‘ir’, ‘raman’,.. or the origin of the data, e.g., ‘omnic’, ‘opus’, … It is often provided by the reader automatically, but can be set manually.

It is used for instance whn reading directory with different types of files, for merging the datasets with compatible dimensions and different origin into different groups.

It is also used when reading with the CSV protocol. In order to properly interpret CSV file it can be necessary to set the origin of the spectra. Up to now only 'omnic' and 'tga' have been implemented.
pattern (str, optional) – A pattern to filter the files to read.

Added in version 0.7.2.
protocol (str, optional) – Protocol used for reading. It can be one of {'scp', 'omnic', 'opus', 'topspin', 'matlab', 'jcamp', 'csv', 'excel'}. If not provided, the correct protocol is inferred (whenever it is possible) from the filename extension.
read_only (bool, optional, default: True) – Used only when url are specified. If True, saving of the files is performed in the current directory, or in the directory specified by the directory parameter.
recursive (bool, optional, default: False) – Read also in subfolders.
replace_existing (bool, optional, default: False) – Used only when url are specified. By default, existing files are not replaced so not downloaded.
sortbydate (bool, optional, default: True) – Sort multiple filename by acquisition date.
