genomic_gaps

Identifier

refseq.genomic_gaps

Description

Gap intervals in top-level RefSeq genomic sequences from assembly-specific *_genomic_gaps.txt.gz reports when NCBI supplies one.

Each row describes a single sequence interval occupied by a gap, including its NCBI gap type and linkage evidence.

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 accession of the top-level sequence containing the gap; joins refseq.assembly_sequences.sequence_accession.
start	INT	1-based inclusive start coordinate of the gap on sequence_accession.
end	INT	1-based inclusive end coordinate of the gap on sequence_accession.
gap_length	INT	Length of the gap in base pairs, as reported by NCBI.
gap_type	TEXT	NCBI classification of the gap, such as within_scaffold, between_scaffolds, telomere, heterochromatin, short_arm, or unknown.
linkage_evidence	TEXT	NCBI evidence supporting the gap, such as paired-ends, within_clone, map, inferred_from_sequence, clone_contig, or unspecified; null when NCBI reports na.
