rnanorm.CUF

class rnanorm.CUF

Counts adjusted with Upper quartile factors normalization.

Procedure for normalization is described in Johnson & Krishnan, 2022, but in short:

• Use raw counts as input

• Compute normalization factors the same way as in UpperQuartile

• Divide raw counts with these factors

Examples

>>> from rnanorm.datasets import load_toy_data
>>> from rnanorm import CUF
>>> X = load_toy_data().exp
>>> X

Sample_1     200     300     500    2000    7000
Sample_2     400     600    1000    4000   14000
Sample_3     200     300     500    2000   17000
Sample_4     200     300     500    2000    2000
>>> CUF().set_output(transform="pandas").fit_transform(X)
