Schema
Section titled “Schema”| Column | Type | Description |
|---|---|---|
sources |
STRUCT(url TEXT, filename TEXT, last_modified_at TIMESTAMPTZ, sha256 TEXT)[] |
Source provenance for the row. |
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. |
