Reimplemented from IMP::Object.

| void IMP::em2d::ProjectionFinder::set_fast_mode | ( | unsigned int | n | ) |
With this fast mode, only the first number n of best scoring projections during the coarse search are refined. Saves vast times of computation time with some loss of accuracy. Try starting with 1 (risky) or 2, and increase it to get more chances of finding the best projection
| void IMP::em2d::ProjectionFinder::set_model_particles | ( | const ParticlesTemp & | ps | ) |
Set the particles where the em2D restraint is applied.
| void IMP::em2d::ProjectionFinder::set_projections | ( | const em2d::Images & | projections | ) |
Set the projections of the model to use for initial coarse correlation.
| void IMP::em2d::ProjectionFinder::set_save_match_images | ( | bool | x | ) |
The projections of the model that best match the subject EM images are saved.
Their name will be: coarse-match-i.spi for coarse registration and fine_match-i.spi for full registration.

| void IMP::em2d::ProjectionFinder::set_subjects | ( | const em2d::Images & | subjects | ) |
Set EM images to use as restraints.
| void IMP::em2d::ProjectionFinder::set_variance_images | ( | const em2d::Images & | variances | ) |
Set the projections of the model to use for initial coarse correlation.
| void IMP::em2d::ProjectionFinder::setup | ( | ScoreFunction * | score_function, |
| const Em2DRestraintParameters & | params | ||
