  return_gobject = TRUE
)

Arguments

gobject

giotto object
expression_values

expression values to use
detection_threshold

detection threshold to consider a gene detected
return_gobject

boolean: return giotto object (default = TRUE)

giotto object if return_gobject = TRUE

Details

This function will add the following statistics to cell metadata:

  • nr_genes: Denotes in how many genes are detected per cell

  • perc_genes: Denotes what percentage of genes is detected per cell

  • total_expr: Shows the total sum of gene expression per cell

Examples
