Schema

Column	Type	Description
sources	STRUCT(url TEXT, filename TEXT, last_modified_at TIMESTAMPTZ, sha256 TEXT)[]	Original external inputs used to produce the row. Each item contains its source URL, filename, HTTP Last-Modified timestamp when available, and computed SHA-256 checksum.
assembly_accession	TEXT	Partition column. Versioned RefSeq assembly accession (GCF accession).
sequence_accession	TEXT	Versioned RefSeq nucleotide sequence accession on which the alteration is located; joins refseq.assembly_sequences.sequence_accession.
start	INT	1-based inclusive start coordinate of the alteration interval.
end	INT	1-based inclusive end coordinate of the alteration interval.
is_forward_strand	BOOLEAN	Whether the alteration interval is on the forward strand; null when the GFF strand is unspecified.
sequence_alteration_id	TEXT	Local GFF3 ID of the alteration; not a stable RefSeq identifier.
alteration_type	TEXT	Source GFF3 alteration type.
annotation_method	TEXT	NCBI GFF column-2 annotation method or source, if supplied.
db_xrefs	STRUCT(db TEXT, id TEXT)[]	Database cross-references from GFF Dbxref; each item has a database and identifier, which may contain colons.
function	TEXT	Free-text functional description from GFF function, if supplied.
experiments	TEXT[]	Percent-decoded experimental-evidence entries from the comma-separated GFF experiment attribute.
note	TEXT	Free-text GFF Note annotation, if supplied.
