This answer is: WebbThe phi and psi values are measured for each amino acid. Each pair of phi, psi values is then mapped on to the nearest grid point. The average phi, psi value of each grid point is then calculated. For e.g., the phi,psi pairs -60.,-40 and -60,-50 would be mapped to the grid point -60,-60. The average phi, psi value is then -60, -45.
