polyester: Polyester: simulating RNA-seq reads including differential expression

Description

Polyester is an R package designed to simulate an RNA sequencing experiment. Given a set of annotated transcripts, polyester will simulate the steps of an RNA-seq experiment (fragmentation, reverse-complementing, and sequencing) and produce files containing simulated RNA-seq reads. Simulated reads can be analyzed using any of several downstream analysis tools.

Arguments

Details

A single function call produces RNA-seq reads in FASTA format from a case/control experiment including biological replicates. Differential expression between cases and controls can be set by the user, facilitating comparisons of statistical differential expression methods for RNA-seq data. See detailed documentation for simulate_experiment and simulate_experiment_countmat.

See the vignette by typing browseVignettes("polyester") in the R prompt.
