class Feature(*, parent: TSeqOrAlign, seqid: str, map: FeatureMap, biotype: str, name: str, strand: int | str, xattr: dict[str, Any] | None = None)

new style annotation, created on demand

Attributes:

biotype

type of biological feature

map

coordinate map and properties of this feature

name

name of the feature

parent

sequence or aligned or alignment

reversed

whether Feature is on the reverse strand relative to bound object

seqid

the sequence id of the parent sequence

xattr

extra attributes for this feature

Methods

as_one_span([name])	returns a feature that preserves any gaps in the underlying sequence
get_children([biotype])	generator returns sub-features of self optionally matching biotype
get_coordinates()	returns sequence coordinates of this Feature as [(start1, end1), ...]
get_drawable()	returns plotly trace
get_parent(**kwargs)	generator returns parent features of self optionally matching biotype
get_slice([complete, allow_gaps, apply_name])	The corresponding sequence fragment.
shadow([name])	returns new instance corresponding to disjoint of self coordinates
to_dict()	returns
union(features)	return as a single Feature
without_lost_spans()	Keeps only the parts which are actually present in the underlying sequence
