Background Subtraction

[phoebe-sch]

Hi! I seem to be having an issue with background substraction. When I add it to the preprocessing protocols pipeline I get the following error:

TypeError: init() takes 1 positional argument but 2 were given

My code is as follows:

import ramanspy as rp import pandas as pd import matplotlib.pyplot as plt import numpy as np

project_directory = "/Users/ps/Documents/GOM GRADients raman/" test_s1d = rp.load.labspec("/Users/ps/Documents/GOM GRADients raman/REAL station 1 drum/s1_d_p1.txt") rp.plot.spectra(test_s1d)

background_test = "/Users/ps/Documents/GOM GRADients raman/si substrate/si_3_102728.txt"

pipe = rp.preprocessing.protocols.Pipeline([rp.preprocessing.misc.BackgroundSubtractor(background_test), rp.preprocessing.denoise.Gaussian()]) preprocessed_test = pipe.apply(test_s1d)

Thanks so much!

Thank you for reaching out!

The background argument of the rp.preprocessing.misc.BackgroundSubtractor.init method is not positional, but a keyword argument. Hence, the BackgroundSubtractor must be initialized as follows:

rp.preprocessing.misc.BackgroundSubtractor(background=background_test)

Note that background_test must be a rp.Spectrum object.
