Detailed Description

The restraint fits the particles into the density map by alignment of principal components of the particles with principal components of the map. Therefore, the particle set should comprise all subunits that fill the map. The aligned particles are scored using EnvelopeScore. This is a fast alignment and scoring that works well for low resolution density maps.

Constructor & Destructor Documentation

IMP::em::EnvelopeFitRestraint::EnvelopeFitRestraint ( Particles  particles,
DensityMap em_map,
double  density_threshold,
double  penetration_threshold 
)
Parameters
[in]particlesThe particles participating in the score
[in]em_mapThe density map used in the fitting score
[in]density_thresholdDensity map threshold
[in]penetration_thresholdA distance for which penetration of particles out of the map envelope (as defined by density_threshold) is allowed. Recommended value is approximately map resolution
