Constructor & Destructor Documentation

def IMP.pmi.restraints.basic.DistanceToPointRestraint.__init__ (   self,
  anchor_point = IMP.algebra.Vector3D(0, 0,
  radius = 10.0,

Setup distance restraint.

root_hierThe hierarchy to select from
tuple_selection(resnum, resnum, molecule name, copy number (=0))
anchor_pointPoint to which to restrain particle (IMP.algebra.Vector3D object)
radiusMaximum distance the particle can move from the fixed point before it is restrained
kappaStrength of the harmonic restraint for point-particle distance greater than the radius
resolutionFor selecting a particle
weightWeight of restraint
labelA unique label to be used in outputs and particle/restraint names
Pass the same resnum twice to each tuple_selection. Optionally add a copy number
