Regress out unwanted sources of variation, using `pp.regress_out`
=================================================================

Regress out unwanted sources of variation, using simple linear regression. This is 
inspired by Seurat's `regressOut` function in R.

More details on the `scanpy documentation
<https://scanpy.readthedocs.io/en/stable/api/scanpy.pp.regress_out.html>`__

Correct batch effects by matching mutual nearest neighbors, using `pp.mnn_correct`
==================================================================================

This uses the implementation of mnnpy. Depending on do_concatenate, it returns AnnData objects in the 
original order containing corrected expression values or a concatenated matrix or AnnData object.

Be reminded that it is not advised to use the corrected data matrices for differential expression testing.

More details on the `scanpy documentation
<https://scanpy.readthedocs.io/en/stable/generated/scanpy.external.pp.mnn_correct.html>`__


Correct batch effects with ComBat function (`pp.combat`)
========================================================

Corrects for batch effects by fitting linear models, gains statistical power via an EB framework where information is borrowed across genes. This uses the implementation of ComBat

More details on the `scanpy documentation
<https://scanpy.readthedocs.io/en/stable/api/generated/scanpy.pp.combat.html>`__
