FTP SITE

Various resources may be downloaded via our FTP site.

Databases:

GenBank:

One can download the most recent full release and/or daily cumulative or non-cumulative update files in flat file format, ASN.1 format, or FASTA format.

RefSeq:

A database of non-redundant reference sequences standards, including genomic DNA contigs, mRNAs, and proteins for known genes. Multiple collaborations, both within NCBI and with external groups, support our data-gathering efforts.

Entrez Gene:

Provides a gene-based view of key genomes and supplies key connections in the nexus of map, sequence, expression, structure, function, citation, and homology data. This database is the successor to LocusLink.

dbSNP:

A database of single nucleotide polymorphisms, small-scale insertions/deletions, polymorphic repetitive elements, and microsatellite variation.

Human Genome Data:

This directory contains one folder for each chromosome, which includes genomic contigs built from finished and unfinished sequence data. The contigs are available in various formats, including ASN.1 format, FASTA format, GenBank flat file format, and GenBank summary format.

Other Genomes:

Data for many genomes, including Map Viewer data, may be downloaded.

Repository of Databases:

UniGene, GeneMap, dbEST, dbGSS, dbSTS,
OMIM, and a number of externally curated and maintained specialized databases.

Taxonomy:

Download taxonomy data for various organisms.

Software:

BLAST:

Download stand-alone sequence comparison software.

Cn3D:

Stand-alone software for viewing structures in three dimensions.

Client / Server Programs:

• Sequin:

  Submission software program for one or many submissions, long sequences, complete genomes, alignments, population/phylogenetic/ mutation studies

• Network-Client BLAST:

  A BLAST client (blastcl3) that accesses the NCBI BLAST search engine. Blastcl3 can search all the sequences in a FASTA file and produce one-to-many alignments in text or HTML format. It can also perform searches against multiple databases.

NCBI Software ToolBox:

A set of software and data exchange specifications used by NCBI to produce portable, modular software for molecular biology.
