## Detailed Description

Fit particles against a set of class averages by principal components.

Compares how well the principal components of the segmented class average fit to the principal components of the particles.

## Constructor & Destructor Documentation

 def IMP.pmi.restraints.em2d.ElectronMicroscopy2D.__init__ ( self, hier, images, pixel_size, image_resolution, projection_number, resolution, micrographs_number = None, n_components = 1 )

Constructor.

Parameters
 hier The root hierarchy for applying the restraint images 2D class average filenames in PGM text format pixel_size Pixel size in angstroms image_resolution Estimated resolution of the images in angstroms projection_number Number of projections of the model to generate and fit to images. The lower the number, the faster the evaluation, but the lower the accuracy resolution Which level of model representation to use in the fit micrographs_number Number of micrograph particles that were used to generate the class averages, if known n_components Number of the largest components to be considered for the EM image
