startRegion {ORFik} | R Documentation |
Get the start region of each ORF. If you want the start codon only,
set upstream = 0 or just use startCodons
.
Standard is 2 upstream and 2 downstream, a width 5 window centered at
start site. since p-shifting is not 100
usually the reads from the start site.
startRegion(grl, tx = NULL, is.sorted = TRUE, upstream = 2L, downstream = 2L)
grl |
a |
tx |
default NULL, a GRangesList of transcripts or (container region), names of tx must contain all grl names. The names of grl can also be the ORFik orf names. that is "txName_id" |
is.sorted |
logical (TRUE), is grl sorted. |
upstream |
an integer (2), relative region to get upstream from. |
downstream |
an integer (2), relative region to get downstream from |
If tx is null, then upstream will be forced to 0 and downstream to a maximum of grl width. Since there is no reference for splicing.
a GRanges, or GRangesList object if any group had > 1 exon.
