title: how to obtain a suitable input file format for weka tool?
body: <p>I am using weka tool to try to generate a set of classification rules from a dataset. The dataset is currently a .txt file of the form: </p>
  
  <pre>webpage attr1 attr2 attr3.....attrn type
  try.html  1     2    3.....</pre>
  
  <p>(with each word seperated by a tab)</p>
  
  <p>How do I convert this to a suitable input file for weka?
  I tried converting it to csv and then to arff format, but it doesn't work and keeps giving me one of 2 errors <code>header stream is invalid</code> or <code>attribute names are not unique</code>.</p>
