Detailed Description

The restraint takes rigid bodies into account, in order to speed up the calculations. Rigid body should be gived as single RigidBody Particle. Other, non-rigid body Particles can also be given.

The shape of a rigid body is assumed to be defined by the set of atom::Hierarchy leaves of the atom::Hierarchy rooted at the rigid body particle.

Algorithmic details:
The distances between the atoms of rigid body do not change, therefore their contribution to the profile is pre-computed and stored.

Parameters
[in]particlesThe particles participating in the fitting score
[in]exp_profileThe experimental profile used in the fitting score
