[antlr-interest] Newick tree grammar help: file has no rules

[Chris Friedline]

Hello,

I'm trying to build a grammar file for parsing newick trees, and am having some issues generating the code from AntlrWorks.  I get an error message like this:

[11:58:47] error(150):  grammar file NewickGrammar.g has no rules 

I've posted my grammar file here: http://pastie.org/2805144

Can anyone help with what might be doing on?

Thanks.
