Average bend angle at each position on a β-strand fragment. Average bend angle at each position on a β-strand fragment for the (a) RL and (b) UD bend angles. The lengths of the β-strands, with three, four, five, six, seven, eight, or nine frames, are represented by the colors, green, purple, orange, cyan, magenta, blue and red, respectively. Symbols (triangle or square) represent β-strands with an odd or even number of frames
