  1. The accuracy of a predicted nucleosome position is measured by sensitivity (Se), specificity (Sp) and F-measure. The improvement of F-measure is computed by comparing with the performance of the pioneer method (Segal method). For DLaNe method, the performance of all 12 structural features is shown in two part, according to their relationship with nucleosome occupancy
