Schematic diagram of move sets. Illustration of different move sets. The circles represent Cα atoms. The axis joining two black circles in each figure represents the axis of rotation of all other involved atoms. The solid line represents the orientation of the Cα atoms before the move and dotted lines represent the orientation of the Cα atoms after the move. The middle dots represent the same figures for two-bead, three-bead and four-bead moves in case of the top row, two-bead and three-bead moves in case of 2nd and 3rd row figures respectively. The move sets in the first three rows are 'local moves' and the 'Rest-all bead move' is a global move.
