#include <IMP/em2d/Em2DRestraint.h>
Inheritance diagram for IMP::em2d::Em2DRestraint:This restraint ensures that a set of particles are similar to a set of EM images. The restraint generates projections of the model that are then compared with the EM images. The projections are generated from the radius of its particles. In the case of atoms, the radius is generated automatically. For other particles the radius has to be provided.

| IMP::em2d::Em2DRestraint::Em2DRestraint | ( | Model * | m | ) |
Creates the restraint. You are not done yet by creating the restraint. After creating it, you need to call the setup() function
|
virtual |
Get any Particle, Container or other ModelObjects read by this during evaluation. If you read everything in a container, you can just return that container.
Implements IMP::ModelObject.
| RegistrationResults IMP::em2d::Em2DRestraint::get_registration_results | ( | ) | const |
Get the registration results for each of the images after finishing the optimization. Obviously, requesting the results before optimizing is an error
Definition at line 131 of file Em2DRestraint.h.
|
virtual |
Get information about the module and version of the object.
Reimplemented from IMP::Object.

| void IMP::em2d::Em2DRestraint::set_coarse_registration_mode | ( | bool | opt | ) |
If the value provided to this function is true, restraint operates only using a coarse registration scheme (maximizing the cross correlation coefficient). This option (which is set to false by default) can speed the evaluation of the restraint by a order of magnitude, but the values obtained are not going to be less accurate. You could want to activate it at the beginning of an optimization.
| opt | true if you want to use the coarse mode |
Definition at line 121 of file Em2DRestraint.h.
| void IMP::em2d::Em2DRestraint::set_fast_mode | ( | unsigned int | n | ) |
Sets fast mode for computing the restraint. This mode only makes sense it the set_coarse_registration_mode option is false. This option only optimizes some coarse results (those given by the argument) to get the refined value. This option is very fast compared to a full optimization, and almost always is a good idea to use it with 1-5 results. This mode is still significantly slow compared to set_coarse_registration_mode(), but the values optimized are optimum.
| n | The number of images to optimize |
| void IMP::em2d::Em2DRestraint::set_images | ( | const em2d::Images | em_images | ) |
Sets the EM images to use as restraints
| em_images | The images |
| void IMP::em2d::Em2DRestraint::set_particles | ( | SingletonContainer * | particles_container | ) |
Sets the particles used to compute projections.
| particles_container | All the particles must be in the container |
| void IMP::em2d::Em2DRestraint::set_variance_images | ( | const em2d::Images | variance_images | ) |
Sets the variance images of EM images. This is useful if the image is a class average Note: Not all the scoring function use this data Sets the variance images for class averages. If class averages are used as restraints, it is possible to use the variance images to assign a standard deviation (error) for each of the pixels in a class average.
| variance_images |
| void IMP::em2d::Em2DRestraint::setup | ( | ScoreFunction * | score_function, |

Initializes the restraint
| score_function | Scoring function to use to evaluate the similarity between particles and projections |
| params | All the parameters required for the restraint |
