Returns the 3’-most coordinate, plus
downstreambp; adds the string
add_to_nameto the feature’s name if provided (e.g., “_polyA_site”)
- featurepybedtools.Interval instance
- upstream, downstreaint
Number of bp upstream or downstream of the strand-specific stop position of the feature to include. Default is 500 for both upstream and downstream so that the returned feature is 1kb centered on the 5’ end of the feature. Unstranded features (where strand=”.”) are treated as plus-strand features.
- add_to_namestr or None
If not None, append the string suffix to the name field of the feature (for example “_TSS”).
- genomedict or None
If not None, then ensure that the start/stop positions are within the boundaries of the chromosome.
