- | radius of curvature: r | kink angle: a length of segments: l1, l2 |
kink angles: a1, a2 twist angle: o lengths of segments: l1, l2, l3 |
The twist angle is measured in the following manner: |
|
The radius of curvature is measured in Å, the kink and twist angles in ° and the segment lengths in base pairs. The models are evaluated using the goodness of fit sigma2.
