title: Weka only changing numeric to nominal
body: <p>I have a CSV file that I am importing into Weka. All variables are importing as numeric. I need to change 3 of them to nominal. However when I place numerictonominal filter on it- all variables change. I only want to change 3. </p>
  
  <p>1) Is there a way to just change a few via the filter
  2) Or can you set it during the import. If so, I can't figure that out either. </p>
