During the computation of a Postion Weight Matrix, the
Position Probability Matrix (derived from a Position Frequency Matrix)
is log transformed. This parameter provides whcih "log transform" will be used.
If TRUE, the Natural Log will bu used (ln). If FALSE, log2 will be used.
We strongly encourage to set values when building a
parameterOptions
