getmatrix - Class: geneont

Convert geneont object into relationship matrix

Syntax

[Matrix, ID, Relationship] = getmatrix(GeneontObj)

Description

[Matrix, ID, Relationship] = getmatrix(GeneontObj) converts a geneont object, GeneontObj, into Matrix, a matrix of relationship values between nodes (row and column indices), in which 0 indicates no relationship, 1 indicates an "is_a" relationship, and 2 indicates a "part_of" relationship. ID is a column vector listing Gene Ontology IDs that correspond to the rows and columns of Matrix. Relationship is a cell array of strings defining the types of relationships.

Inputs

GeneontObj A geneont object, such as created by the geneont constructor function.

Outputs

`Matrix`	Matrix of relationship values between nodes (row and column indices), in which `0` indicates no relationship, `1` indicates an "is_a" relationship, and `2` indicates a "part_of" relationship.
`ID`	Column vector listing Gene Ontology IDs that correspond to the rows and columns of `Matrix`.
`Relationship`	Cell array of strings defining the types of relationships.

Examples

Download the current version of the Gene Ontology database from the Web into a geneont object in the MATLAB software.
```
GO = geneont('LIVE',true) 
```
The MATLAB software creates a geneont object and displays the number of terms in the database.
```
Gene Ontology object with 27595 Terms.
```
Convert this geneont object into a relationship matrix.
```
[MATRIX, ID, REL] = getmatrix(GO); 
```
