Annotation

Defined in: node_modules/.pnpm/betula-schema@0.6.0/node_modules/betula-schema/dist/types.d.ts:113

A GFF3-derived sequence feature (gene model) node. Shared verbatim between picea (SequenceInterval) and react-bio-viz (SequenceInterval). seqid/start/end/strand stay flat rather than nesting under core/Location, to match the real current wire shape exactly.

This interface was referenced by Betula’s JSON-Schema via the definition “Annotation”.

Properties

Property	Type	Description
type?	"annotation"	Wire-format object-kind discriminator (see betula’s versioning policy). Optional. Distinct from ‘interval_type’: ‘type’ says this is a betula Annotation object, ‘interval_type’ says which GFF3 feature kind it is.
ID	string	-
seqid	string	-
source	string	GFF3 column 2.
interval_type	string	GFF3 column 3 (feature type), e.g. ‘gene’, ‘mRNA’, ‘exon’, ‘CDS’.
start	number	GFF3 column 4: 1-based inclusive start.
end	number	GFF3 column 5: 1-based inclusive end.
score	number | "."	GFF3 column 6. ‘.’ is the GFF3 convention for ‘no score’.
strand	"-" | "." | "+"	GFF3 column 7.
phase	0 | 2 | 1 | "."	GFF3 column 8 (CDS reading-frame phase). ‘.’ is the GFF3 convention for ‘not applicable’.
attributes	Metadata	-
children	Annotation[]	Nested features, e.g. mRNA under gene, exon/CDS under mRNA.
