Valid options are:

 -D Turns off the normalization of attribute  values in distance calculation.

 -R <col1,col2-col4,...> Specifies list of columns to used in the calculation of the  distance. 'first' and 'last' are valid indices. (default: first-last)

 -V Invert matching sense of column indices.
