Rigid-body description of the NMSM transition in terms of subdomain screw-axis transformations.

Vectors vˆ and correspond to the position and orientation of the screw axis, scalars φ and d to the rotation angle and the translational shift involved in the screw-axis transformation, respectively. The screw axes for individual subdomains were determined as described in Text S4. The last column reports the intermolecular distances between the centers of mass (com) of the corresponding subdomains of the rigor-like and the NMSM conformation.
