Function

Find GO ontology terms by definition

Description

godef searches the definition of gene ontology terms and returns matching terms. The input is read from the installed GO database. The ontology term output can be written to screen, to file, or passed to another program. A wide range of standard ontology term formats may be specified for input and output.

Optionally the search can be restricted to specified GO namespaces.

Usage

Here is a sample session with godef


% godef glycoprotein

Input file format

godef queries the gene ontology.

Output file format

The output is a standard EMBOSS ontology term 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: obo, brief, list, html, xml, json, excel.

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