assemblies

registry.assemblies

Canonical identity for selected current and historical GenBank genome assemblies.

One row per versioned GenBank assembly accession.

genbank_assembly_accession is the exact canonical key. refseq_assembly_accession is a paired alias when NCBI provides one. assembly_name is NCBI’s exact asm_name, while assembly_build and assembly_patch are populated only for GRC-style names ending in .p<number> (for example, GRCh38.p14 becomes GRCh38 and p14).

Not partitioned.

Column Type Description
assembly_name TEXT Exact NCBI assembly name (asm_name), including a patch where applicable (for example, GRCh38.p14).
assembly_build TEXT Broader GRC-style build name derived from assembly_name (for example, GRCh38); null when no .p<number> patch suffix is present.
assembly_patch TEXT GRC-style patch component derived from assembly_name (for example, p14); null when no .p<number> patch suffix is present.
organism_taxon_id TEXT NCBI taxonomy identifier for the organism from which the assembly was derived; joins registry.taxa.taxon_id.
species_taxon_id TEXT NCBI taxonomy identifier for the assembly’s species; joins registry.taxa.taxon_id.
genbank_assembly_accession TEXT Versioned GenBank assembly accession (GCA); the unique canonical key.
refseq_assembly_accession TEXT Paired versioned RefSeq assembly accession (GCF), if NCBI provides one.
