chromosomes

Identifier

ensembl.chromosomes

Description

Reference chromosome intervals and their Ensembl GFF3 aliases.

One row per chromosome.

Always filter on genbank_assembly_accession (partition column). chromosome is the raw GFF3 sequence ID for these records; it is known to be a chromosome rather than a scaffold or contig.

Schema

Column	Type	Description
sources	STRUCT(url TEXT, filename TEXT, last_modified_at TIMESTAMPTZ, sha256 TEXT)[]	Provenance for the GFF3 feature records.
release	TEXT	Ensembl release number the annotation was drawn from.
genbank_assembly_accession	TEXT	Partition column. GenBank assembly accession (partition column).
chromosome	TEXT	Ensembl chromosome name from the GFF3 sequence ID (e.g. 1, X, or MT).
aliases	TEXT[]	Alternate chromosome names from the comma-separated GFF3 Alias attribute, including INSDC accessions when supplied.
is_circular	BOOLEAN	Whether the GFF3 Is_circular attribute marks the chromosome as circular. May be null when the attribute is absent.
start_position	INT	1-based start coordinate of the chromosome interval.
end_position	INT	1-based end coordinate of the chromosome interval.
chromosome_source	TEXT	Annotation source in GFF3 column 2 (often the assembly name).
