public class PartitionedMultiFilter extends SimpleBatchFilter implements WeightedInstancesHandler, WeightedAttributesHandler

Valid options are: 

 -D
  Turns on output of debugging information.
 
 -F <classname [options]>
  A filter to apply (can be specified multiple times).
 
 -R <range>
  An attribute range (can be specified multiple times).
  For each filter a range must be supplied. 'first' and 'last'
  are valid indices. 'inv(...)' around the range denotes an
  inverted range.
 
 -U
  Flag for leaving unused attributes out of the output, by default
  these are included in the filter output.
