Hi -
Can you post the entire stack trace and the version of biojava you are
using to the list (not direct to me as I'm not an expert on this API)?

Subject: [Biojava-l] Trouble with GOParser
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
