    from cana.datasets import getspectrum
    import cana

    # First load an spectrum
    # you can do: spec = cana.loadspec('path to your spectrum file')

    # For the example, we will just gonna use one from the available datasets.


    spec = getspectrum('000334', ref='primass')

    # Measuring the slope
    # Defaults: wmin=0.4, wmax=0.9, norm=0.55, errormethod='rms',
    #           error_param=None, montecarlo=1000, speckwargs=None
    slope = cana.slope(spec)

    # print the results
    print(slope)

    # plot the results
    slope.plot(show=True)

    # Note: cana.slope can also get the direct spectrum file path,
    # or a list of spectra file. In this case it would return the a
    # pandas table with results.
