Normalize total counts per cell (`pp.normalize_per_cell`)
=========================================================

Normalize each cell by total counts over all genes, so that every cell has
the same total count after normalization.

Similar functions are used, for example, by Seurat, Cell Ranger or SPRING.

More details on the `scanpy documentation
<https://icb-scanpy.readthedocs-hosted.com/en/stable/api/scanpy.pp.normalize_per_cell.html>`__


Normalization and filtering as of Zheng et al. (2017), the Cell Ranger R Kit of 10x Genomics (`pp.recipe_zheng17`)
==================================================================================================================

Expects non-logarithmized data. If using logarithmized data, pass `log=False`.

The recipe runs the following steps:

- only consider genes with more than 1 count
- normalize with total UMI count per cell
- select highly-variable genes
- subset the genes
- renormalize after filtering
- log transform (if needed)
- scale to unit variance and shift to zero mean

More details on the `scanpy documentation
<https://icb-scanpy.readthedocs-hosted.com/en/stable/api/scanpy.pp.recipe_zheng17.html>`__


Normalization and filtering as of Weinreb et al (2017) (`pp.recipe_weinreb17`)
==============================================================================

Expects non-logarithmized data. If using logarithmized data, pass `log=False`.

More details on the `scanpy documentation
<https://icb-scanpy.readthedocs-hosted.com/en/stable/api/scanpy.pp.recipe_weinreb17.html>`__


Normalization and filtering as of Seurat et al (2015) (`pp.recipe_seurat`)
==========================================================================

This uses a particular preprocessing.

Expects non-logarithmized data. If using logarithmized data, pass `log=False`.

More details on the `scanpy documentation
<https://icb-scanpy.readthedocs-hosted.com/en/stable/api/scanpy.pp.recipe_seurat.html>`__
