Description

Filter scRNA-seq data based on the primary QC metrics.
This is based on both the UMI counts, the gene counts
and the mitochondrial genes (genes starting with mt/MT).

Inputs

Name	Type & Properties	Description
--input	file required	Input h5mu file
--modality	string	Which modality from the input MuData file to process.
--layer	string	Location of the count matrix. If specified, will be used to select a key from .layers, otherwise .X is used.

Outputs

Name	Type & Properties	Description
--output	file output	Output h5mu file.
--do_subset	boolean_true	Whether to subset before storing the output.
--obs_name_filter	string	In which .obs slot to store a boolean array corresponding to which observations should be removed.
--var_name_filter	string	In which .var slot to store a boolean array corresponding to which variables should be removed.
--output_compression	string	Compression format to use for the output AnnData and/or Mudata H5 files. By default no compression is applied.
