Creates an instance of S4 class TxFeatures for storing
transcript features.
Usage
TxFeatures(x, type = mcols(x)$type, txName = mcols(x)$txName, geneName = mcols(x)$geneName)
Arguments
x
GRanges with known strand (+, -)
type
Character vector or factor, taking value
J, I, F, L, or U
txName
CharacterList of transcript names or NULL
geneName
CharacterList of gene names or NULL
Value
TxFeatures object
Details
TxFeatures extends GRanges with column slot type
specifying feature type. type is a factor with levels
J (splice junction), I (internal exon),
F (5' terminal exon), L (3' terminal exon),
U (unspliced transcript).
txName and geneName are CharacterLists storing
transcript and gene annotation, respectively.
