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.

Note

Constructor.

Parameters
representationDEPRECATED, pass 'hier' instead
images2D class average filenames in PGM text format
pixel_sizePixel size in angstroms
image_resolutionEstimated resolution of the images in angstroms
projection_numberNumber of projections of the model to generate and fit to images. The lower the number, the faster the evaluation, but the lower the accuracy
micrographs_numberNumber of micrograph particles that were used to generate the class averages, if known
resolutionWhich level of model representation to use in the fit
n_componentsNumber of the largest components to be considered for the EM image
hierThe root hierarchy for applying the restraint
