用于去除背景荧光/噪声的BaselineRemoval套装

Question

我正在尝试使用BaselineRemoval包从一些拉曼光谱中去除背景荧光。在代码文档中，它将输入的首选格式声明为input_array: A pandas dataframe column provided in input as dataframe['input_df_column']. It can also be a Python list object

我的例子-

df = pd.DataFrame(
{'Patient': [1, 2, 3, 4, 5, 6],
'Group': [1, 1, 1, 2, 2, 2],
'Samples': [list(np.random.randn(3).round(2)) for i in range(6)]
}
)
input_array = df['Samples']
polynomial_degree = 2
baseObj = BaselineRemoval(input_array)
Modpoly_output = baseObj.ModPoly(polynomial_degree)

然而，这给出了错误ValueError: setting an array element with a sequence.

不确定如何继续。

Answer 1

一个简单的for循环就可以完成。

df = pd.DataFrame(
{'Patient': [1, 2, 3, 4, 5, 6],
'Group': [1, 1, 1, 2, 2, 2],
'Samples': [list(np.random.randn(3).round(2)) for i in range(6)]
}
)
input_array = df['Samples']
polynomial_degree = 2
for row in input_array:
print(BaselineRemoval(row).ModPoly(polynomial_degree))
