  1. Impact of the three motif operations (described in Table 7) measured by the correlation of the significance measures with the values of Sn and length. The former is used to simulate generalizations and specializations and the latter extensions to the number of concrete symbols of the motif. For measures with constant score values no correlation value is provided.
