title: Unable to determine structure as arff in WEKA
body: <p>I tried the proposed solutions online by saving the file in ANSI and deleting the first line and changing the attributes to numeric instead of real as follows and even by adding a '}' symbol at the line 29 but I still get the following error in WEKA when I try to import the arff file. </p>
  
  <p>Error Message:</p>
  
  <p>Unable to determine structure as arff(Reason:java.io.IOException: } expected at end of enumeration, read Token[EOL],line 29)</p>
