Arguments

object

Seurat or LIGER object

...

Arguments passed to other methods

species

Species of origin for given Seurat Object. If mouse, human, marmoset, zebrafish, rat, drosophila, or rhesus macaque (name or abbreviation) are provided the function will automatically generate mito_pattern and ribo_pattern values.

mito_name

name to use for the new meta.data column containing percent mitochondrial counts. Default is "percent_mito".

ribo_name

name to use for the new meta.data column containing percent ribosomal counts. Default is "percent_ribo".

mito_ribo_name

name to use for the new meta.data column containing percent mitochondrial+ribosomal counts. Default is "percent_mito_ribo".

mito_pattern

A regex pattern to match features against for mitochondrial genes (will set automatically if species is mouse or human; marmoset features list saved separately).

ribo_pattern

A regex pattern to match features against for ribosomal genes (will set automatically if species is mouse, human, or marmoset).

mito_features

A list of mitochondrial gene names to be used instead of using regex pattern. Will override regex pattern if both are present (including default saved regex patterns).

ribo_features

A list of ribosomal gene names to be used instead of using regex pattern. Will override regex pattern if both are present (including default saved regex patterns).

ensembl_ids

logical, whether feature names in the object are gene names or ensembl IDs (default is FALSE; set TRUE if feature names are ensembl IDs).

overwrite

Logical. Whether to overwrite existing meta.data columns. Default is FALSE meaning that function will abort if columns with any one of the names provided to mito_name ribo_name or mito_ribo_name is present in meta.data slot.

list_species_names

returns list of all accepted values to use for default species names which contain internal regex/feature lists (human, mouse, marmoset, zebrafish, rat, drosophila, and rhesus macaque). Default is FALSE.

assay

Assay to use (default is the current object default assay).

Value

An object of the same class as object with columns added to object meta data.

Examples

if (FALSE) {
# Liger
liger_object <- Add_Mito_Ribo(object = liger_object, species = "human")
}

if (FALSE) {
# Seurat
seurat_object <- Add_Mito_Ribo(object = seurat_object, species = "human")
}
