convertToTxFeatures {SGSeq} | R Documentation |
Convert a TxDb
object or a GRangesList
of exons
grouped by transcripts to a TxFeatures
object.
convertToTxFeatures(x)
x |
|
If x
is a GRangesList
, transcript names and gene names
can be specified as character vectors in metadata
columns txName
and geneName
, respectively.
If missing, transcript names are based on names(x)
.
For import from GFF format, use function importTranscripts
.
In the returned TxFeatures
object, column type
takes
values “J” (splice junction), “I” (internal exon),
“F” (5'/first exon), “L” (3'/last exon) or “U”
(unspliced).
