Hello,

I am having some troubles wiht GOParser class. I would like to use it in order to load an ontology and then display this ontology in a JTree.

This is the code I am testing:

try {
BufferedReader file = new BufferedReader(new FileReader("po_anatomy.ontology"));
       OntologyFactory factory = OntoTools.getDefaultFactory();
GOParser parser = new GOParser(); Ontology onto = parser.parseGO(file, "trait", "description", factory);
       } catch (Exception e) {System.out.println(e);};

When I execute it, I get a java.lang.NullPointerException. The line causing the exception is the parseGO(...) one. Do you have any idea? I am able to read perfectly the ontology with Dag-Edit.

Thanks in advance,

Óscar D. Sánchez
