**What it does**

This tool converts data from a GenBank_ flat file format to GFF (scroll down for format description).

- The following data in GenBank format::

**About file formats** 

**GenBank format** An example of a GenBank record may be viewed here_

.. _here: http://www.ncbi.nlm.nih.gov/Sitemap/samplerecord.html 

**GFF** Generic Feature Format is a format for describing genes and other features associated with DNA, RNA and Protein sequences. GFF lines have nine tab-separated fields::

    1. seqid - Must be a chromosome or scaffold or contig.
    2. source - The program that generated this feature.
    3. type - The name of this type of feature. Some examples of standard feature types are "gene", "CDS", "protein", "mRNA", and "exon".
    4. start - The starting position of the feature in the sequence. The first base is numbered 1.
    5. stop - The ending position of the feature (inclusive).
    6. score - A score between 0 and 1000. If there is no score value, enter ".".
    7. strand - Valid entries include '+', '-', or '.' (for don't know/care).
    8. phase - If the feature is a coding exon, frame should be a number between 0-2 that represents the reading frame of the first base. If the feature is not a coding exon, the value should be '.'.
    9. attributes - All lines with the same group are linked together into a single item.
