The GenBank (aka Genetic Sequence Data Bank) sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations.[1][2] This database is produced at National Center for Biotechnology Information (NCBI).

Statistics

  • GenBank Flat File Release 164.0 (2008-02-15)
    • 82,853,685 loci, 85,759,586,764 bases, from 82,853,685 reported sequences.[3]
    • Uncompressed, the Release 164.0 flatfiles require roughly 321 GB (sequence files only) or 342 GB (including the 'short directory', 'index', and the *.txt files).
  • GenBank Flat File Release 161.0 (2007-08-15)
    • 76,146,236 loci, 79,525,559,650 bases, from 76,146,236 reported sequences.[3]
    • Uncompressed, the Release 161.0 flatfiles require roughly 299 GB (sequence files only) or 319 GB (including the 'short directory', 'index', and the *.txt files).
  • GenBank Flat File Release 158.0 (2007-02-15)
    • 67,218,344 loci, 71,292,211,453 bases, from 67,218,344 reported sequences.[3]
    • Uncompressed, the Release 158.0 flatfiles require roughly 251 GB (sequence files only) or 263 GB (including the 'short directory', 'index', and the *.txt files).

Note: You can find the current release number by issuing the following commmand: 

lynx --dump ftp://ftp.ncbi.nih.gov/genbank/GB_Release_Number

GenBank entries in the eukaryotic database

Flat file features

The following documents describe in detail the features of various flat files:

Index files

The index keys (accession numbers, keywords, authors, journals, and gene symbols.) of an index are sorted alphabetically. Following each index key, the identifiers of the sequence entries containing that key are listed (LOCUS name, division abbreviation, and primary accession number). The division abbreviations are:

  1. PRI - primate sequences
  2. ROD - rodent sequences
  3. MAM - other mammalian sequences
  4. VRT - other vertebrate sequences
  5. INV - invertebrate sequences
  6. PLN - plant, fungal, and algal sequences
  7. BCT - bacterial sequences
  8. VRL - viral sequences
  9. PHG - bacteriophage sequences
  10. SYN - synthetic sequences
  11. UNA - unannotated sequences
  12. EST - EST sequences (expressed sequence tags)
  13. PAT - patent sequences
  14. STS - STS sequences (sequence tagged sites)
  15. GSS - GSS sequences (genome survey sequences)
  16. HTG - HTGS sequences (high throughput genomic sequences)
  17. HTC - HTC sequences (high throughput cDNA sequences)
  18. ENV - Environmental sampling sequences
  19. CON - Constructed sequences
