I have seen references to minimization of a jump edge (e.g using a MinMover object) leading to both rotations and translations downstream of the jump.
I am modelling an interaction between two proteins, connected in the fold tree by a single jump edge, with atom pair constraints defined to bring them into close proximity.
I allow movement of this jump in the movemap (set_jump), atom_pair_constraints is activated in the scorefunction, and the fold tree is valid.
When I apply a MinMover (or indeed an AtomTreeMinimizer object) I get rotation of the downstream protein but no translation (change in the distance along the jump).
Is this expected behaviour? Or are there known instances where the minimization of the jump distance fails?
Many thanks
