title: Weka exception: Can't open file iris.arrf
body: <p>I am trying to run a script from command line for Weka classification task, it is working perfectly for training CSV data. But for Arrf file it is not working.</p>
  <p>Command:</p>
  <pre><code>java -cp &quot;C:\Program Files\Weka-3-8-5\weka.jar&quot; weka.classifiers.trees.J48 -t iris.arrf
  </code></pre>
  <p>Error: <strong>Weka exception: Can't open file iris.arrf.</strong></p>
  <p>The Iris file is the sample data obtained from Weka/data folder so I don't know where is the issue.</p>
