- **-out**

  \<string\>         Output vector data file containing the reduced vector  (optional, off by default)

- **-feat**

  \<string list\>    Input features to use for reduction.  (mandatory, no default value)

- **-featout**

  \<string\>         Output feature \[prefix/list\] (mandatory, default value is prefix)
