Constructor & Destructor Documentation

IMP::npctransport::FGChain::FGChain	(	IMP::Particle *	root,
		double	backbone_k = 0.0,
		double	rest_length_factor = 1.0,
		std::string	name = "chain %1%"
	)

initialized an FG chain with given backbone k and rest length factor, and a specified root whose leaves are the beads of the chain.

Parameters

root	root of the chain (leaves are assumed beads). can be null = to be added later
backbone_k	force constant between consecutive chain beads
rest_length_factor	equilibrium distance factor between consecutive beads relative to the sum of their radii
name	chain object name

Here is the call graph for this function:

virtual Restraints IMP::npctransport::FGChain::get_chain_restraints ( Scoring const *  scoring_manager )

virtual

Returns a restraint associated with internal interactions by this chain. Once this method has been called once, it is assumed that the chain topology remains static (the behavior of the restraint if the chain topology changes is undefined, e.g. if beads are added)

Note

this restraint is affected by future calls to set_rest_length_factor() and set_backbone_k(). However, it applies only to the topology of the chain at the time of call, if the chain topology changes, this methods should be called again.

assumes that the chain has a valid root whose leaves are beads
