Get mapping between transcripts and genes

This function uses the biomaRt package.

getTx2gene(
  dataset = "mmusculus_gene_ensembl",
  version = NULL,
  outputDir = "data"
)

Arguments

dataset	Ensembl gene dataset, passed to `biomaRt::useEnsembl()`. To see which datasets are available, do `mart = biomaRt::useEnsembl('genes'); biomaRt::listDatasets(mart)`.
version	Passed to `biomaRt::useEnsembl()`.
outputDir	Directory in which to save the result, a file named "tx2gene.csv". If `NULL`, no file is saved.

A data.frame, as returned by biomaRt::getBM().
