Constructor & Destructor Documentation

IMP::em::FitRestraint::FitRestraint ( ParticlesTemp  ps,
DensityMap em_map,
FloatPair  norm_factors = FloatPair(0., 0.),
FloatKey  weight_key = atom::Mass::get_mass_key(),
float  scale = 1,
bool  use_rigid_bodies = true,
KernelType  kt = GAUSSIAN 
)
Parameters
[in]psThe particles participating in the fitting score
[in]em_mapThe density map used in the fitting score
[in]norm_factorsif set, they are used as normalization factors for the cross correlation calculations. This is relevant when the cross-correlation score of the entire system is decomposed.
[in]weight_keythe name of the weight attribute of the particles
[in]scalemultiply the fitting restraint score and derivatives by this value
[in]use_rigid_bodiesif some of the particles are part of a rigid body, use the rigid body for faster calculations
[in]ktKernelType to use for simulating density from particles
Note
Rigid-bodies are interpolated and not resampled if use_rigid_bodies option is selected. This significantly reduces the running time but is less accurate. If the user prefers to get more accurate results, provide its members as input particles and not the rigid body.
