   'bia'  <line>|<set> [ [<bias>] [<factor>]|
                   ['mult'|'div' <factor>] ]
This keyword is used to define the bias of a single line or of a set of lines (see qadd). The bias defines the ratio of the length of the first element to the length of the last element. For example,

bia all 4.5

will force a ratio in which the last element is 4.5 times bigger than the first one. Real numbers are permitted since version 1.5 (see also qbia). To convert from pre 1.5 versions, start the program with the -oldbias option. A negative factor permits to invert the direction of the bias:

bia all 4.5 -1
