scprep 0.9.0

scprep

Tools for loading and preprocessing biological matrices in Python.

Installation

preprocessing is available on pip. Install by running the following in a terminal:

pip install --user scprep

Alternatively, scprep can be installed using Conda (most easily obtained via the Miniconda Python distribution):

conda install -c bioconda scprep

Usage example

You can use scprep with your single cell data as follows:

import scprep
# Load data
data_path = "~/mydata/my_10X_data"
data = scprep.io.load_10X(data_path)
# Remove empty columns and rows
data = scprep.filter.remove_empty_cells(data)
data = scprep.filter.remove_empty_genes(data)
# Filter by library size to remove background
scprep.plot.plot_library_size(data, cutoff=500)
data = scprep.filter.filter_library_size(data, cutoff=500)
# Filter by mitochondrial expression to remove dead cells
mt_genes = scprep.utils.get_gene_set(data, starts_with="MT")
scprep.plot.plot_gene_set_expression(data, mt_genes, percentile=90)
data = scprep.filter.filter_gene_set_expression(data, mt_genes,
                                                percentile=90)
# Library size normalize
data = scprep.normalize.library_size_normalize(data)
# Square root transform
data = scprep.transform.sqrt(data)
