getTssFromGTF(
  source,
  convertEnsemblUCSC = FALSE,
  destDir = NULL,
  filterProteinCoding = TRUE
)

Arguments

source

a string that is either a path to a local or remote GTF

convertEnsemblUCSC

a logical indicating whether Ensembl style chromosome annotation should be changed to UCSC style

destDir

a string that indicates the path to the directory where the downloaded GTF file should be stored

filterProteinCoding

a logical indicating if TSSs should be only protein-coding genes (default = TRUE)

Value

a list of GRanges objects
