Function

Get descendants of taxon(s)

Description

taxgetdown reads in one or more taxons, finds all taxons below in tyhe hierarchy, and writes them out. 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.

Algorithm

The NCBI taxonomy records the parent of each taxon, up to a known top level 1.

Usage

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:9605' is a sequence entry in the example taxonomy database 'ttax'

Database entry: ttax:9605

id: 9605
parent: 207598
rank: genus
emblprefix: 
division: 5
divflag: 1
gencode: 1
gcflag: 1
mitocode: 2
mgcflag 1
hidden: 1
nosequence: 1
scientific name: Homo
authority: Homo Linnaeus, 1758

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.

Output files for usage example
