## Function

Find EDAM ontology terms by definition

## Description

edamdef searches the definition of EDAM terms and returns matching terms. The input is read from the installed EDAM 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 EDAM namespaces.

## Usage

Here is a sample session with edamdef

    % edamdef multiple
    Find EDAM ontology terms by definition
    Obo output file [edamdef.obo]:

Go to the output files for this example

Example 2

    % edamdef multiple -subclasses
    Find EDAM ontology terms by definition
    Obo output file [edamdef.obo]:

## Input file format

edamdef queries the EDAM 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.

Haplotype comparison is a useful way to characterize the genetic variation between individuals.

Tools might use combinatorial functions (for example parsimony) or a likelihood function or model with optimization such as minimum error correction (MEC) model, expectation-maximization algorithm (EM), genetic algorithm or Markov chain Monte Carlo (MCMC).
