Sequin A DNA Sequence Submission and Update Tool

Sequin version 3.32 is now available by anonymous FTP.

What is Sequin
Sequin is a stand-alone software tool developed by the NCBI for submitting and updating entries to the GenBank, EMBL, or DDBJ sequence databases. It is capable of handling simple submissions which contain a single short mRNA sequence, and complex submissions containing long sequences, multiple annotations, segmented sets of DNA, or phylogenetic and population studies. Getting Started with Sequin is a very brief overview of the program.

A Quick Guide to Sequin
This short demonstration, newly updated, of how to use Sequin is derived from the August 1996 issue of the NCBI News, and includes a section on how to prepare your sequence data files before you begin preparing your sequence submission with Sequin.

Sequin Help Documentation
A window containing the Sequin Help Documentation is opened when the Sequin program is launched. The contents of this scrolling window change as you move within the Sequin program, presenting you with help documentation appropriate for the section of Sequin you are presently visiting. This documentation is also available in a World Wide Web format.

How to Get Sequin
Sequin 3.32 is currently available from the EBI. Sequin runs on Macintosh, PC/Windows, and UNIX computers. Instructions for downloading and installing the program are provided. The program itself, along with its on-line help documentation, is available by anonymous FTP.

Network Aware Sequin
Sequin can be used in one of two modes, stand-alone, or network-aware. In the network-aware mode, the program can exchange data between any computer connected to the Internet and the NCBI. Network-aware Sequin allows users to:

Update their own existing database records
Perform a PowerBLAST search
Screen their sequence for contamination with vector or mitochondrial sequence
Perform a Medline lookup
Perform a Taxonomy lookup
Use the NCBI DeskTop
