## Function

Get taxon(s)

## Description

taxget reads in one or more taxons and writes them out again. The taxon input may be a literal sequence or read from a database, file, file of taxon names, or even the command-line or the output of another programs. The taxon output can be written to screen, to file, or passed to another program. A wide range of standard taxon formats may be specified for input and output.

## Usage

Here is a sample session with taxget

    % taxget ttax:9606
    Get taxon(s)
    Taxon output file [9606.tax]:

## Input file format

The input is a standard EMBOSS taxonomy query.

The expected source of taxonomy information is the NCBI Taxonomy database "taxon" which is available as a standard database in all EMBOSS installations.

Data can also be read from taxonomy output in "ncbi" format written by an EMBOSS application.

See: http://emboss.sf.net/docs/themes/TaxonFormats.html for further information on taxon formats.

### Input files for usage example

'ttax:9606' is a sequence entry in the example taxonomy database 'ttax'

### Database entry: ttax:9606

    id: 9606
    parent: 9605
    rank: species
    emblprefix: HS
    division: 5
    divflag: 1
    gencode: 1
    gcflag: 1
    mitocode: 2
    mgcflag 1
    hidden: 1
    nosequence: 1
    scientific name: Homo sapiens
    authority: Homo sapiens Linnaeus, 1758
    genbank common name: human
    common name: man

## Output file format

The output is a standard EMBOSS taxon file.

The results can be output in one of several styles by using the command-line qualifier `-oformat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: ncbi, ebi, tax, excel.

See: http://emboss.sf.net/docs/themes/TaxonFormats.html for further information on taxon formats.
