phenoSimulate: PhenoPath simulation

In Oshlack/splatter: Simple Simulation of Single-cell RNA Sequencing Data

PhenoPath simulation

Description

Simulate counts from a pseudotime trajectory using the PhenoPath method.

Usage

phenoSimulate(params = newPhenoParams(), sparsify = TRUE, verbose = TRUE, ...)

Arguments

params	PhenoParams object containing simulation parameters.
sparsify	logical. Whether to automatically convert assays to sparse matrices if there will be a size reduction.
verbose	logical. Whether to print progress messages
...	any additional parameter settings to override what is provided in params.

Details

This function is just a wrapper around simulate_phenopath that takes a PhenoParams, runs the simulation then converts the output from log-expression to counts and returns a SingleCellExperiment object. The original simulated log-expression values are returned in the LogExprs assay. See simulate_phenopath and the PhenoPath paper for more details about how the simulation works.

Value

SingleCellExperiment containing simulated counts
