genome_nucleotides

Identifier

refseq.genome_nucleotides

Description

Individual nucleotide positions from assembly-specific *_genomic.fna.gz files.

Each row represents one 1-based position on a RefSeq genomic sequence.

Source lowercase bases are normalized to uppercase IUPAC nucleotide codes and retained through is_masked as RefSeq soft-masking information.

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 genomic sequence; joins refseq.assembly_sequences.sequence_accession.
position	INT	1-based nucleotide position on sequence_accession.
nucleotide	TEXT	Uppercase IUPAC DNA nucleotide code at position.
is_masked	BOOLEAN	Whether the nucleotide is soft-masked in the source RefSeq genomic FASTA, indicated by a lowercase base.
