Table 3.

The initial angle differences between domain pairs of all test proteins. One can select the proper relative rotation pair by checking the initial values. In the case of Lactoferrin, one can select the domains pairs as one of the initial angle difference near zero. The domain pairs which relative rotation exceed 150 degree can be wiped out. (Unit: degree)
