 -W classname <br>
 Specify the full class name of a classifier (required).<p>

 -C cost file <br>
 File name of a cost matrix to use. If this is not supplied, a cost
 matrix will be loaded on demand. The name of the on-demand file
 is the relation name of the training data plus ".cost", and the
 path to the on-demand file is specified with the -N option.<p>

 -N directory <br>
 Name of a directory to search for cost files when loading costs on demand
 (default current directory). <p>

 -I num <br>
 Set the number of bagging iterations (default 10). <p>

 -S seed <br>
 Random number seed used when reweighting by resampling (default 1).<p>

 -P num <br>
 Size of each bag, as a percentage of the training size (default 100). <p>

 Options after -- are passed to the designated classifier.<p>
