Subject: Classifying a single file after training the model
 
1. Index the training data that I've pre-classified manually . Then perform
training and testing. Everything works fine to this point



This seems to work (looking at the confusion matrix  even though these are
plan old text snippets as opposed to newsgroup text articles.

2. At this point, I want to classify individual files that are not part of
the training set. I've tried a bunch of things that don't seem to work.
For example, .. I try to invoke main() on  TestNewsGroups.java
<http://svn.apache.org/repos/asf/mahout/trunk/examples/src/main/java/org/apache/mahout/classifier/sgd/TestNewsGroups.java>
  
with the args



and end up with an Exception


Any idea what I can do to fix this? Thanks
