sequence_annotations
Identifier
Section titled “Identifier”Description
Section titled “Description”RefSeq sequence-level annotations from explicit genomic GFF3 rows. annotation_type preserves the source
type; the table name avoids ambiguity with the literal sequence_feature source type.
A source ID can label multiple intervals.
Partitions

Schema
Section titled “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 annotation is located; joins refseq.assembly_sequences.sequence_accession. |
start |
INT |
1-based inclusive start coordinate of the annotated interval. |
end |
INT |
1-based inclusive end coordinate of the annotated interval. |
is_forward_strand |
BOOLEAN |
Whether the annotated interval is on the forward strand; null when the GFF strand is unspecified. |
sequence_annotation_id |
TEXT |
Local GFF3 ID of the annotation; not a stable RefSeq identifier and can recur across intervals. |
annotation_type |
TEXT |
Source GFF3 sequence-annotation feature 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. |
annotation_name |
TEXT |
Annotation name from GFF standard_name, if supplied. |
associated_gene_symbol |
TEXT |
Gene symbol from GFF gene, if supplied; this is not a local GFF gene-ID join. |
allele_name |
TEXT |
Allele name from GFF allele, if supplied. |
is_pseudogene |
BOOLEAN |
Whether GFF pseudo=true marks the annotation as pseudogenic. |
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. |
is_partial |
BOOLEAN |
Whether NCBI marks the annotation as partial with GFF partial=true. |
is_start_partial |
BOOLEAN |
Whether NCBI marks the column-4 start boundary as partial with GFF start_range. |
is_end_partial |
BOOLEAN |
Whether NCBI marks the column-5 end boundary as partial with GFF end_range. |
note |
TEXT |
Free-text GFF Note annotation, if supplied. |
