**-i**\ *cols*\ [**l**\ ][\ **s**\ *scale*][\ **o**\ *offset*][,\ *...*]
    Select specific data columns for input, in arbitrary order. Columns
    not listed will be skipped. Give columns (or column ranges)
    separated by commas [Default reads all columns in order, starting 
    with the first column (0)]. To each column, optionally add any of 
    the following, in this order: **l** takes the **log10** of the input
    values first; **s**\ *scale*, subsequently multiplies by a given 
    scale factor; **o**\ *offset*, finally adds a given offset.
