Seurat (version 1.2.1)

tobit.test: Differential expression testing using Tobit models

Description

Identifies differentially expressed genes between two groups of cells using Tobit models, as proposed in Trapnell et al., Nature Biotechnology, 2014

Usage

tobit.test(object, cells.1, cells.2, genes.use = NULL, thresh.use = log(2))

Arguments

object
Seurat object
cells.1
Group 1 cells
cells.2
Group 2 cells
genes.use
Genes to test. Default is to use all genes.
thresh.use
Limit testing to genes which show, on average, at least X-fold difference (log-scale) between the two groups of cells.

Increasing thresh.use speeds up the function, but can miss weaker signals.

Value

Returns a p-value ranked matrix of putative differentially expressed genes.
