You are right, it does seem to assume that the rigid body and hierarchy particles are the same. Not a good assumption in general. I think it is quite easily fixed (by having the constructor get the rigid body from the passed particle). However, there don't seem to be any testing of rigid bodies in saxs, so it is hard to be sure of the patch. Dina?

Patch to saxs::Restraint::Restraint add: else if (core::RigidMember::particle_is_instance(particles[i])) { rigid_bodies_decorators_.push_back(core::RigidMember(particles[i]).get_rigid_body()); rigid_bodies_.push_back(ref->get_refined(particles[i])); // compute non-changing profile Profile rigid_part_profile; rigid_part_profile.calculate_profile(rigid_bodies_.back(), ff_type); rigid_bodies_profile_.add(rigid_part_profile); }

Since the method is not documented or supported and has other areas where it doesn't work right, I'm not terribly motivated to fix it and would rather simply remove it.
