Length distribution of helices and strands assigned by stride, psea and kaksi. Length distribution of helical (top) and extended (bottom) segments assigned by STRIDE (plain line and crosses), PSEA (dashed line and open circles), and KAKSI (dotted line and filled circles), on the HRes set. The STRIDE assignment generates a large number of 3 residue-long helices (1238 segments) and 1 residue-long strands (corresponding to 1800 β-bridges).
